This test checks that running `slapos node software` command on theia
shell starts installing software, but this command might get an error
like:

    process started, but another slapos process is aleady running with pid 2656158, exiting

this happened for example with https://erp5js.nexedi.net/#/test_result_module/20240911-ED8B4BF9/60

This test uses XMLRPC to control ERP5

- Each class now correspond to an instance with different configuration,
and possibly several test methods.
- Upgraded to more recent pypdf version.
- The code has been reviewed to reduce complexity and repetition.
- Adds documentation to all public functions, in Google style.
- Some other cosmetic changes have been made for
consistency (consistent parentheses indentation, consistent string
literal quotes), courtesy of ruff.

The `enable-scripting` parameter allows to specify a LibreOffice script
to be applied before saving the document, as per
cloudooo@a09d87af
If false (the default), an exception will be raised instead.

This commit also adds two SlapOS integration tests classes to test the
functionality:
- TestScripting requests an instance with scripting enabled, and tests
the scripting functionality.
- TestScriptingDisabled tests that scripting fails if it is not enabled
explicitly.

The option "ooo_enable_scripting" can now be set up in the
generic.cloudooo recipe.
This option allows the Cloudooo server to execute user scripts to edit
the documents before they are saved
(see cloudooo@a09d87af).

Fix clone favicon being the same as the main instance favicon - this
is an uncaught regression. Add a test for it. Also give each clone a
different favicon, in case there are several clones.

When using older GCC versions (e.g. 8.3.0), Inkscape fails with an error
similar to:

```C++
/srv/slapgrid/slappart15/srv/runner/instance/slappart7/tmp/shared/inkscape/31c6ae5c72c5325d479cca38e62b82bb/.build/inkscape-1.3.2_2023-11-25_091e20ef0f/src/ui/tools/booleans-subitems.cpp: In lambda function:
/srv/slapgrid/slappart15/srv/runner/instance/slappart7/tmp/shared/inkscape/31c6ae5c72c5325d479cca38e62b82bb/.build/inkscape-1.3.2_2023-11-25_091e20ef0f/src/ui/tools/booleans-subitems.cpp:213:61: error: cannot deduce template arguments for ‘uniform_real_distribution’ from ()
     auto ranf = [&] { return std::uniform_real_distribution()(gen); };
```

This may be an instance of this problem:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81486

In any case, setting a minimum version of 10.5 for GCC when building
Inkscape, as done in this commit, seems to fix this.

This is based on example from https://json-schema.org/understanding-json-schema/reference/object#unevaluatedproperties
this approach allows extending a schema from another software type with
some extra properties while rejecting other properties on instances,
like it's done with additionalProperties: false.

Currently librsync is being compiled in the folder lib64 in some
OSes (e.g. SUSE SLE 15.6).
This is a problem because some dependents look for the library in the
lib subdirectory.
This change forces librsync to always use the lib directory.

this binary is no longer used

because we are not using anymore and no new release was made to fix
CVE-2024-38428

wget is only used for a peertube self-upgrade script that we do not use

also cleanup to not explitly list parts, having the parts automatically
installed when they are referenced is less maintenance.

wget was used for varnish, which we removed in 24a91de4 (Get rid of
unused/unsupported software type., 2013-07-10). It was still installed
because of this remaining unused reference.

wendelin.core 2.0.alpha3.post22 supports being installed by newest

The rapid-cdn software.cfg manually downloads/copies a setup.py and
a software.py into a folder and then installs it as a develop egg.

Installing a develop-egg creates a .egg-info or a .dist-info into
the source folder.

In rapid-cdn/software.cfg an update-command resulted in the folder
being deleted and recreated on every update for no gain. This also
deleted the .egg-info or .dist-info, breaking the develop egg
installation.

With the zc.buildout 3.0.1+slapos003 release, zc.recipe.egg:develop
is now able to detect such cases and trigger the reinstallation of
the .egg-info or .dist-info. Still, this update-command remains the
cause of useless computations.

Test that slapos-testing compiles and instantiates for each Python
version (software.cfg, software-py2.cfg, software-py3next.cfg).

Donwgrade scipy to be compatible with the version of numpy pinned
in software/monitor - itself downgraded to be compatible with the
version of statsmodels currently pinned to 0.11.1. Upgrading this
will first require adjusting the code in slapos.toolbox that uses
statsmodels, as the next version has breaking changes in the API.

Version up scipy=1.12.0 because scipy 1.8.1 is not compatible with
Python 3.11.

This is a generalisation of macro.pythonpath.eggs which allows paths
from eggs to be placed into any environment variable, and provides a
way to specify subpaths for each egg from the egg location.

Like macro.pythonpath.eggs, the environment variable is placed in an
environment section at install time after the eggs are installed and
before the environment section is read by the section which uses it.

```
[environment-section]
PATH = some/path

[modify-environment]
<= macro.variable.eggs
variable = ANY_VARIABLE
eggs =
  blue_egg
  yellow_egg
  red_egg
subpaths =
  blue_egg subpath/specific/to/blue
  yellow_egg subpath/specific/to/yellow

[section-that-uses-environment]
recipe = zc.recipe.egg:custom
environment = environment-section
depends =
  ${modify-environment:recipe}

```

In case of unavailable backend 502 and 503 are the possible codes, so relax
the assertion.

Move the versions of matplotlib, matplotlib-inline and cycler pinned in
component/matplotlib/buildout.cfg to slapos.cfg.
The cycler version for Python 3.7 will be upgraded to 0.11.0 as it is
compatible.

One reason motivating this change is that the version of `cycler` in
stack/slapos.cfg is overriding the version specified in
component/matplotlib/buildout.cfg for the erp5-zope2 software release.
This is a problem because the former does not take into account the
Python version, while the later does.
Thus, attempting to compile erp5-zope2 would give the following error:

```
Getting distribution for 'cycler==0.11.0'.
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.
ERROR: Package 'cycler' requires a different Python: 2.7.18 not in '>=3.6'
While:
  Installing matplotlib.
  Base installation request: 'cycler', 'python-dateutil', 'numpy'
  Getting distribution for 'cycler==0.11.0'.
```

This adds the right version of `cycler` for Python 2 in `slapos.cfg`, so
that it does not fail.
