There can be a short delay after the request until the request is logged, so
wait a bit more before inspecting the log.

There can be lines from requests made in previous tests, so make sure to only
read the last line.

Since haproxy checks backend is up at an inteval or 3 seconds with a timeout
of 3 seconds, it can happen that the server reply in a bit more of 3 seconds
and haproxy mark it as down.

By using a shorter response time in test, we can achieve the same test coverage
without this race condition and test runs a bit faster.

Since we don't use caucase yet, it's necessary to make sure this feature is
not lost.

This resource is just a certificate, not necessary a certificate to use as
client.

The test expecting that X-Forwarded-For is empty can also accept the
case where X-Forwarded-For header is not present.

Further work by Vincent Pelletier:
- do not enable openldap dependency, we do not need such advanced features
  (yet ?)
- refresh noroot.patch
- if we this component is to reference m4, then it should extend it

Fixes FTBFS on gcc 10.

This upgrade mainly fixes gpython and pymain to be more compatible with
CPython when handling command line. In particular it moves
sys.executable setup and -O handling into pymain:

pygolang!10
pygolang@21756bd3
pygolang@11b367c6
pygolang@8564dfdd

in ceb063a4 (software/repman: tests python3 compliance, 2020-10-23), test
profile was changed to run on python3 only but this was accidentally
reverted in 3a1e5628 (software/slapos-sr-testing: use nxdtest, 2020-10-28),
by running repman also on python2.

Restore the situation where we run repman only on python3

The initial intent was to use an interpreter named `python_for_test` and not
`python`, so that software do not accidentally pick up this python during
compilation.
6033e4fa (software/slapos-sr-testing: fix python3 profile, 2020-12-01)
was a quick fix for some python3 compatibility issues discovered after merge,
but it was not correct, because by using ${python-interpreter:eggs}, it was
installing the default python-interpreter section, which has an interpreter
named `python`.

This caused issues while building proxysql, which assumes /usr/bin/env python
is python2.

The fix is to override python-interpreter directly, we don't need another
section eggs here.

This code seems not used, before 51c3773e and b77d7bae it was not possible to import.

the version up is needed to support more CPU architectures. For example,
version 0.2.18 was failing with Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz

This code error when it's imported, because it imports from a non existing,
slapos.tool module.
This is an "emergency commit" to repair the tests on python 3 after

This code error when it's imported, because `install` does not exist on
this class, so the assignment caused NamError.

This is to match Theia file hierarchy

Until now, standalone subsystem was started as a daemon first time a terminal
was openned and since it was running as daemon, stopping the theia instance
did not stop any of the services running in the embedded slapos.

Before nexedi/slapos.core!265 there was
two supervisor running as daemon:
 - ~/srv/slapos/etc/supervisord.conf which runs slapos proxy etc
 - ~/srv/slapos/inst/etc/supervisord.conf with runs instances in the embedded
   slapos
After, the second one runs as a service in the first one, but the first one
was still running as daemon.

This changes so that the first supervisor runs as a service managed by the
Theia instance, so stopping Theia instance will effectively stop the services.

When upgrading, running instances should continue to run as detached. To
attach them to the new service, procedure could be something like this

Stop supervisors inside Theia instance:

  supervisorctl -c ~/srv/slapos/etc/supervisord.conf shutdown
  supervisorctl -c ~/srv/slapos/inst/etc/supervisord.conf shutdown

Restart slappartX:slapos-standalone-instance-XXX-on-watch from host slapos
