This reverts commit 3d12ddae.

The commit was instroducing errors in compilation or at runtime.

Compilation error were like (for cmake in Debian 8 machine):
[ 99%] Built target CTestLib
[100%] Built target ctest
Install the project...
bin/cmake: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by bin/cmake)

Makefile:72: recipe for target 'install' failed
make: *** [install] Error 1
cmake: Command 'set -e;make  install' returned non-zero exit status 2
cmake: Compilation error. The package is left as is at /srv/slapgrid/slappart61/srv/runner/shared/cmake/9fc4b0e8f4f03ce17eb7ef43525d2238__compile__/cmake-3.7.2 where you can inspect what went wrong.

Runtime errors were like (for mariadb in Debian 9):
Traceback (most recent call last):

Be nice test and clean up your own mess.

~/bin/slapos script does not overwrite $SLAPOS_CONFIGURATION if it's set,
to prevent service accidentally use another slapos.cfg if $SLAPOS_CONFIGURATION
is set for some reason, explicit pass the path of the slapos.cfg

This solves vulnerabilities reported by npm upon installation.

We'd prefer ld to always take LD_RUN_PATH into account, even if any
rpath is specified in the command-line. We could actually change the
wrapper this way but it would not be consistent with the case where
the SR is built with system gcc.

This is quite an ugly workaround

This addresses both :
 - some random failures we sometimes have when installing `python-language-server` fail
 - caddy no longer being installed here since nexedi/slapos!821

See merge request nexedi/slapos!828

It has to be ensured, that parameters are correctly passed to the partitions.

Each node allows for global statistic access for full backend-haproxy, which
is exposed using special frontend, and then transferred back to the master
partition, so that the administrator can access it.

Prevent this kind of errors when first installation fail:

    Error: [Errno 13] Permission denied: 'parts/python-language-server/bin/activate'

by using --clear the virtualenv is recreated from scratch if the command failed
for some reason.

We are observing mariadb crashes in ERP5 with 10.4, so revert back to 10.3

Crashes errors are:

    InnoDB: Assertion failure in file .../mariadb-10.4.14/storage/innobase/lock/lock0lock.cc line 6900

in non debug mode and:

    mysqld: .../mariadb-10.4.14/storage/innobase/row/row0sel.cc:4480: dberr_t row_search_mvcc(byte*, page_cur_mode_t, row_prebuilt_t*, ulint, ulint): Assertion `prebuilt->sql_stat_start || trx->state == TRX_STATE_ACTIVE || (prebuilt->table->no_rollback() && trx->state == TRX_STATE_NOT_STARTED)' failed.

in debug mode.

This is an incompatible change for ERP5 instances which might have
already been running mariadb 10.4, because their database would have
been updated to 10.4, but mariadb does not support "downgrading".
Hopefully we don't have such cases, but if that's the case one
solution seems to dump databases with 10.4 and load in 10.3 and
I guess in this process the system databases such as "mysql" should
be excluded from this process.

Changes:

 * traffic_cop was removed, so use traffic_manager directly
 * logging.config was changed to logging.yaml
 * made records.config and storage.config similar to original files
 * proxy.config.admin.synthetic_port option was removed
 * proxy.config.process_manager.mgmt_port option was removed
 * test: ignore traffic.out in logs
 * test: update ATS version
 * pqsn field was removed and replaced with shn, so follow upstream:
   https://github.com/apache/trafficserver/commit/b0969c91ebc52b37f4c3195ec17d4d0c1c18650c
 * add a test to prove squid.log working, as upgrade resulted with not
   created file

Require minially gcc 8 for C++17 support

Copied part of gowork.install:command to activate GO111MODULES and also the
[caddy] section is minimised, as the whole build happnes in proper place.

defines 'configure-command = true' because configure script does not exist

Should be used soon.

There was missing promise from other work.

This is critical feature of SlapOS Master instantiation, and very easy to
damage, thus testing it is important.

It's useful for some tests to use.

Some profiles needs to extends the path with binaries location of provided
software.
