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

Now that "the bug in the way promises are run" referenced in the comment
in ${template:test} is being fixed, we can start running ERP5 with
python3 slapos.

This was using master branch and when it got renamed to main this
stopped working and we realized that the revision was not pinned.

Also fix a few typos and type annotations

KVM which defaults to 1024 RAM, 10 GB disk and 1 CPU is too small for nowadays
OS requirements, so to avoid confusions, increase the defaults.

Because of a bug in checkSoftware ( nexedi/slapos.core!339 ) we did not check some .so for missing rpath.

Add the missing rpaths now that these are correctly detected by checkSoftware

Sometimes on testnodes hugo refuses to start because:

    Error: add site dependencies: create deps: failed to create file caches from configuration: mkdir /tmp/hugo_cache/default: permission denied
