chore(tests): Liveliness probe & diagnostics in tenant DB checkout (#2185)

* chore(tests): Liveliness probe & diagnostics in tenant DB checkout

## Main Goal
Addressing our most common/annoying flakies:
the one where the tests are just killed, best to our knowledge because
we failed to acquire a tenant DB.

Now, before handing out a database we run a small probe that the DB
is healthy.

The same probe is also now run to declare the container ready for the
pool.

If it is unhealthy, we discard it so a new one can be started, so in
theory this should self-heal and help eliminate errors.

## Diagnostics
Also we now keep the docker containers around instead of deleting them
(`--rm`), so we can diagnose what killed them.

Hope to be able to use these diagnostics/logs from the container, to
track down the actual source of the issues and fix that as well.

Sadly, this means we also need to manually clean them up in the end.

* chore(tests): Add more diagnostics based on live failure report

See our time stamp, more CPU information and a longer log.

* chore: unless --> if
