This definition was extract from tesnode, and can be reused to generate a
simple log() funcional for several others tools.

Implement a common library to connect to ERP5 Task Distribution Tool, this should be
the central place for use this.

This is surely the source of random duplicate uid problems. Indeed,
some test like testERP5Catalog using default extra_sql_connection_string_list
provided by slapos were using same connection string as other running tests

This way, we can effectively kill all subprocesses. This worked for
slapproxy because Flask calls setsid internally, but slapgrid-* doesn't, so
they wouldn't be killed by killpg.

Fixes upgrade path from older erp5testnode version.

Note that it is useless to test simulation quantity in isSimulated
because even if it exists, we already failed to find a related SM.

This will be required to fix a possible race condition in causality_workflow

Otherwise, first test may fail if '--random_activity_priority=' option is used.

This fix is already applied to erp5.util.testnode, we duplicate
the fix. The code will move to library soon

The stop_condition() check is run once every beginning of loop tic, but if a loop
achieved a state of total failure, RuntimeError was raised before stop_condition()
had a chance to run.

So we call it again just one more time to see if we can avoid failing.

the code of some id generator can raise ValueError when objects
are not fully installed, and this is typically a case when the
compatibility code needs to run (like uid generation in the middle
of the installation of id generators objects)

This is used to get ongoing status even though there is no failures,
it allows to know what is going on on testnode side

This fix errors that could depend on environment (like python
version, mariadb version, etc)

The test was randomly failing since we were not getting last modification
date exactly the same way as the zope webdav support

Allow to override and address every individual menu item.

Css fixes.
