Use simple string and internal process, and caddy instances are not kept
simple and are not considered future-proof.

The setup "last,libc,none" allows lazy resolving of backend servers which is
crucial in order to being able to start when the domain does not exists (yet).

There was missing change in the default value to calculate default maximum
amount of parameters.

This fixes commit 2e6ccd02.

The default virtio-net-pci is not supported by some legacy OSes, so allow
customize it, to provide such support.

This is a dependency of slapos.cookbook[test] since 90650d2c (
recipe/test_postgres: test with a real postgres server, 2021-11-12) and
because we run software schema tests from slapos.cookbook in
software/slapos-sr-testing, we also need the dependency here.

tests with a real postgresql server, the mocked commands from 261a8e6b (test/recipe: update tests for postgres recipe regarding password update, 2021-11-11) were too unrealistic.

These tests with a real server revealed that the port option of the recipe was not used, this is fixed as well

See merge request nexedi/slapos!1083

even though the recipe has a required option for port, it was not used
and server was always listening on default (5432) port

exposing environment variable SLAPOS_TEST_POSTGRESQL_PREFIX containing
the location where postgresql is installed

Go1.17 is current stable Go release which, besides other improvements,
compared to Go1.16 generates code that runs 5-10-15% faster(*):

https://go.dev/blog/go1.17

It makes sense to use that version by default.

Cc'ing people who might be affected:

- caddy   (@luke)
- hugo    (@lu.xu)
- repman, restic  (@alain.takoudjou, @jerome)
- galene  (@tomo, @alain.takoudjou)
- gitlab  (@alain.takoudjou, @jerome, @lpgeneau)
- grafana (@jerome)
- theia   (@jerome, @xavier_thompson)

If for some reason Go1.17 default does not work for a software,
maintainer of that software release - please pin Go to Go1.16
explicitly inside that particular software-release.

(*) Go blog mentions 5% speedup on the average, but it was reported that
    sometimes for important inner loops the speedup can be as much as 15%.

The history of deploy script can be seen in slapos.core package with:
git log -p master/bt5/slapos_web_deploy/PathTemplateItem/web_page_module/deploy_*

When server is running, use psql command to connect to server and issue
a query to update password.

Going Go1.16.8 -> Go1.16.10 brings in fixes to compiler, runtime and stdlib
including security fixes to linker, archive/zip package.

https://golang.org/doc/devel/release.html#go1.16.minor

Tested via:

- SlapOS.SoftwareReleases.IntegrationTest.Python2 (https://nexedijs.erp5.net/#/test_result_module/20211110-4DA2B2E), and
- SlapOS.SoftwareReleases.IntegrationTest.Python3 (https://nexedijs.erp5.net/#/test_result_module/20211110-40489859)

Going Go1.17.1 -> Go1.17.3 brings in fixes to compiler, runtime and stdlib
including security fixes to linker and archive/zip package.

In 805374b4 I established the way to run wendelin.core test.  There
component/wendelin.core/test-common.cfg preamble mimics what is setup
by software/neoppod/software-common.cfg in parts for NEO. However I
copied only neoppod into parts without neoppod-develop, and this results
in NEO being installed from PyPI instead of from git checkout.

Let's fix this because everything else - e.g. ERP5 and Wendelin software
releases - use NEO from git checkout which today diverged significantly
from what was last released to PyPI in April of 2019.

Thanks to @jerome for helping to find this out.

- it's not used in a SlapOS system (seems only used for webcam support)
- it breaks the concept of SlapOs containerization
- finally it tries to create a DBUS file in /etc/dbus-1/system.d/ which is NOT
  allowed (rightfully) for a slapsoft user

This allow caucase test use the random partition IP
address instead of fixed localhost:8000. Which can avoid
the conflict if one test node running multiple test suite.

 - use the requests.Session in a context manager so that resources are
properly closed.
 - close the stdout of caucase process we want to keep silent

See merge request nexedi/slapos!1075

This is used by caucase.sh test

%Tt was not good, because it also included the idle time from previous
request when the connection was reused, causing times recorded in log
files to be much longer the actual request duration.

%Ta - which is described as total active time for the HTTP request,
between the moment the proxy received the first byte of the request
header and the emission of the last byte of the response body - is much
more suitable for our use case of measuring requests durations and is
similar to apache's %D

Since nexedi/slapos.core!329 we can run use a python3 slapos.core

This reverts commit d7721eb4.

The change didn't fix the real problem.

There is no reason to wait before banging the partition if VNC is not
available, as reprocessing is the only way to fix the situation.

This allows to synchronise server position of the mouse with the client one,
thus making mouse really usable.
