Sometimes container or service does not start, and this
doesn't make the CI fail. Until now, the failed containers
are listed in the /var/log/extras/ tree, but it's not
checked on a regular basis.
This patch intends to make a hard failure in case either
a service or a container doesn't start as expected.
