software/ors-amarisoft: Merge instance-ue-lte.jinja2.cfg + instance-ue-nr.jinja2.cfg  -> into instance-ue.jinja2.cfg

This is preparatory step for MultiRU and removes code duplication.

Mostly straightforward, but there is one backward incompatible change: instead
of ue_lte_config_link and ue_nr_config_link there is now only one
ue_config_link parameter.

We talked with Lu some time ago and my understanding is that UEsim is not widely
used. This way I think it is better to clarify things instead of putting
backward compatibility effort for nothing.

As Amarisoft documentation says in UEsim LTE bandwidth is defined in MHz, nor in RB:

    https://tech-academy.amarisoft.com/lteue.doc#prop.bandwidth

I checked the history and it was like this since 2015-10-28 release.

By coincidence this removes last usage of C Preprocessor from ue.jinja2.cfg
and, similarly to enb.jinja2.cfg, makes it to be Jinja2-only.

To support multiple Radio Units and multiple cells, we will need to loop over them
and emit corresponding configuration parts taking RU/Cell parameters into
account for each part. We currently handle some such parameters at Jinja2 level
(e.g. dl_earfcn), while some other parameters at CPP level (e.g. cell
bandwidth) and rely on enb to preprocess generated enb.cfg with CPP on its own.

While CPP works ok for simple 1RU-1CELL cases, and CPP is also the tool that Amarisoft
itself uses in its examples, it has the limitation that it cannot cooperate
with loops. In other words there can be only one global N_RB_DL #define, and it
cannot be different for different cells while we are looping over them at
Jinja2 level. That means that we cannot use CPP to handle multiple cells.

For this reason switch enb.jinja2.cfg to be using Jinja2 only without CPP.

While rendered enb.cfg/gnb.cfg change, we can see that they change in expected
way, with leaving only blocks that should be active for input parameters. See
the Appendix for details.

The switch is straightforward but one thing deserves to be mentioned: due to
limitation of Jinja2, where macros can return only strings, we use JSON
encoding to be able to return arbitrary types - integers, floats, dicts, etc,
and use a convention to name such macros with j prefix and wrap their usage
with J so that whole invocation does not add much noise. See added slaplte.J
documentation for details.

In the next patch we will switch usage of C Preprocessor to Jinja2, and in jinja2 doing set from under if, as e.g. in

    {%- if ru == 'm2ru' %}
    {%-   set n_antenna_ul = 1  %}
    {%- endif %}

does _not_ have the effect of setting n_antenna_ul=1 outside of the if block.

That, however, can be worked around with usage of namespace objects, so the following works as intended:

    {%- set x = namespace() %}
    {%- if ru == 'm2ru' %}
    {%-   set x.n_antenna_ul = 1  %}
    {%- endif %}

with x.n_antenna_ul=1 if ru was m2ru.

So taking into account this, and that in MultiRU ru will be denoting
RadioUnit-related configuration, let's switch ru to be a namespace object with
ru.ru_type denoting type of attached radio unit.

This both goes as a preparatory step for MultiRU and also allows to switch from
CPP to Jinja2 in the next patch.

and stop using old version in gitlab

software/ors-amarisoft: enb.jinja2.cfg: nr: Move tunable parameters from nr_cell_default to nr_cell_list

This patch is similar and has the same rationale as the previous patch
(software/ors-amarisoft: enb.jinja2.cfg: lte: Move tunable parameters
from cell_default to cell_list). Please see its description for context
and details.

Like with previous patch I've made sure via json_util that effective gnb
configuration stays exactly the same. Also, since for NR case we move
more code, and also use enb merging feature(*) I tested that the
effective gnb configuration stays exactly the same with both

  * tdd_config = 3  (5ms 8UL 1DL 2/10 (maximum uplink)),	and
  * tdd_config = 1  (5ms 2UL 7DL 4/6 (default))

In all the cases effective gnb configuration stayed exactly the same
before and after this patch which proves that effective configuration
for single cell case remains unchanged.

(*) enb implements merging process for cell/cell_default and
nr_cell/nr_cell_default as demonstrated below:

  cell={a: 10, d:15}  cell_default={a:1, b:2, c:3}       ->  cell={a:10, b:2, c: 3, d: 15}
  cell={x: [{}, 2]}   cell_default={x: [{a:1}]}          ->  cell={x: [{a:1}, 2]}
  cell={x: [{c:11}]}  cell_default={x: [{a:1}, {b:2}]    ->  cell={x: [{a:1, c:11}, {b:2}]}

/cc @lu.xu, @tomo, @xavier_thompson, @Daetalus
/reviewed-by @jhuge
/reviewed-on nexedi/slapos!1515

Currently we set some cell tunable parameters on the cell object itself
(e.g. dl_earfcn), while other cell tunable parameters on the
cell_default object, e.g. cell bandwidth. This works ok when there is
only one cell, but with multiple cells it makes a problem because
different cells can have e.g. different bandwidth.

So as preparatory step for MultiRU move the code, that sets tunable
parameters for lte cells, from cell_default to cell object itself.

Rendered config changes but we can verify that the configuration, that
enb actually uses, stays the same: When enb starts it builds internal
configuration for all configured cell objects by merging cell_default +
cell's explicit configuration and using the result as the actual
configuration for the cell. There is no more cell_default in that actual
configuration. And also enb emits that actual runtime configuration in
the beginning of enb.log which we can extract and investigate(*)

So this way we can run enb with old and new generated enb.cfg and then
compare the actual configuration. It turns out to be empty:

    ~/enb# ./lteenb -n x/old/enb.cfg
    ...
    RF0: sample_rate=11.520 MHz dl_freq=1910.000 MHz ul_freq=1910.000 MHz (band 33) dl_ant=2 ul_ant=2
    (enb) quit
    ~/enb# mv log/enb.log log/enb.log.old

    ~/enb# ./lteenb -n x/out/enb.cfg
    ...
    RF0: sample_rate=11.520 MHz dl_freq=1910.000 MHz ul_freq=1910.000 MHz (band 33) dl_ant=2 ul_ant=2
    (enb) quit
    ~/enb# mv log/enb.log log/enb.log.new

    ~/enb# ../ots/json_util log log/enb.log.old >a
    ~/enb# ../ots/json_util log log/enb.log.new >b
    ~/enb# diff -u a b  # output is empty

which means that effective enb configuration before and after this patch is exactly the same.

For the reference, how internal configuration looks like is provided in the appendix.

P.S. for now I do not plan to expose full measurement configuration in
     the generic MultiRU and so it stays in cell_default with corresponding TODO.

So that it is possible to try running enb on generated configs becuase
with previous numbers enb refuses to start:

    ~/enb# ./lteenb  x/old/enb.cfg
    ...
    x/old/enb.cfg:50: field 'dl_earfcn': range is [0:262143] (LTE Cell #0)

    ~/enb# ./lteenb  x/old/gnb.cfg
    ...
    x/old/gnb.cfg:54: invalid frequency band (NR Cell #1)

We need enb to be able to start with generated config because enb dumps in its
enb.log the real configuration that it builds from cell_list + cell_default and
nr_cell_list + cell_default - which is possible to extract via `json_util` and
which we want to check after our changes to enb.jinja2.cfg to see if we
really don't introduce semantic mistakes when e.g. moving things in between
cell_default to cell_list (see next patch).

With new frequencies enb and gnb both start ok.

For example there is no slaptap under StandaloneSlapOS and <RU>-netconf-socket
promise needs real RU hardware to be around and accepting incoming connections.

If we don't wrap such things with `if not testing` running test on testnodes will fail.

Less need to keep default synchronized and less noise in the code. We will need
to refer to `testing` more in the next patch, so it will help a bit.

Similarly to f365a440 (software/ors-amarisoft: Merge gnb.jinja2.cfg into
enb.jinja2.cfg) merge LTE and NR configuration files for UEsim into single
config as the preparation for MultiRU - there UEsim will be also handling TDD,
FDD, LTE and NR cells and UEs all at the same time.

In this patch for now we only move code without changing it and wrap parts with
`if do_lte` and `if do_nr` correspondingly.  The end result of rendered
ue-lte.cfg and ue-nr.cfg stays practically the same as shown in the appendix.

We are going to generate more and more type of files via slapos-render-config:
currently we generate only enb.cfg and gnb.cfg, but soon it will be also
ue-*.cfg, drb_*.cfg, asn etc.

So it will be handy to easily separate generated files from their source, to
make snapshots of generated stuff for comparison, and to also e.g. to be able
to copy generated configs to a callbox/simbox for testing.

-> Move the place where generated files are emitted from config/ to config/out/

Now that we have a more modern firefox, it requires secure context for
many things. This fixes `TypeError: crypto.subtle is undefined` test
failures for JIO.

While not faulty in itself, f365a440 caused ors-amarisoft testsuite to start failing with

    ERROR: test_gnb_conf (testTDD.TestGNBParameters1)
    ----------------------------------------------------------------------
    Traceback (most recent call last):
      File ".../slapos-repository/software/ors-amarisoft/test/testTDD.py", line 298, in test_gnb_conf
        test_gnb_conf1(self)
      File ".../slapos-repository/software/ors-amarisoft/test/testTDD.py", line 184, in test_gnb_conf1
        self.assertEqual(conf['tx_gain'], gnb_param_dict1['tx_gain'])
    KeyError: 'tx_gain'

( https://erp5js.nexedi.net/#/test_result_module/20240119-1C2BDD94/45 )

This happens because previously gnb.jinja2.cfg emitted tx_gain/rx_gain and everything else for SDR case when `ru != "m2ru"`:

    https://lab.nexedi.com/nexedi/slapos/blob/d078060c/software/ors-amarisoft/config/gnb.jinja2.cfg#L22-55

while enb.jinja2.cfg had this only under `if bbu == "ors"`:

    https://lab.nexedi.com/nexedi/slapos/blob/d078060c/software/ors-amarisoft/config/enb.jinja2.cfg#L44-114

so since bbu != "ors" when tests are run via `testTDD.py` and `testFDD.py`
(and `testTDD-ORS.py` is not  ran at all as I explained in nexedi/slapos.toolbox!129)
this resulted in gnb.cfg not to have tx_gain/rx_gain for bbu != ors case and
corresponding test failure.

There is no real problem for ORS since for `bbu==ors` tx_gain/rx_gain are emitted.

-> Fix testsuite to pass again similarly to how it was done in b32b4a8e
   (software/ors-amarisoft: general improvement for RU (logs/promises/input
   parameters) for now).

In the future ORS case will be verified by dedicated test_ors.py which will
have checks for tx_gain and rx_gain unconditionally applied, while support for
all other cases will be handled by generic test.py which will have different
logic for how rf_driver section is generated and verified.

This makes urljoin works as expected and generally makes sense because
this is a collection.
