Reduce default log level for Ceph template and
related overlays.
Log level 20 is highly verbose and fills up the log files
pretty quickly. With loglvel=20, osd log files
(/var/log/ceph/ceph-osd.*.log) have reached ~20G in ~8
hours.
Reduce loglevels down to 1 based on Dan's(hillpd) comment:
"Ceph supports run-time logging level changes. It is easy
enough to use `ceph tell` or the daemon socket to
raise/lower log levels across a reproducer.
I'd recommend dropping the level all the way down to 1 by
default.
This will also reduce overall stress on stsstack -- ceph
can be very verbose at raised debug levels."
Don't exclude namespaces charms from revision-info
Most charms release to cs:<charm> as their stable whereas
others use cs:~<team>/<charm> so we need to allow that
when using --release-info.
One remaining caveat here is that if the revision-info uses
a namespaced charm but the template does not then it will
not be matched. That will either require a manual edit to
fix (--replay) or we need to update the template in question
to use the namespaced charm.
We currently expect charm version info given to
--revision-info to be for stable charms and as
a result we silently ignore any charm that is
not cs:<charm>. This patch displays a message
showing any charms whose version is ingored
and if no versions are found, does not switch
to --use-stable-charms.
The final exit code of this script is non-zero when it's success.
When grep fails (i.e. no unbound variables), it exits immediately
because of -e option. || ensures that grep failure doesn't exit the
script and also explicitly exit with 0. Otherwise, "last command"'s
(= grep) return code will be used for exit code which is non-zero.
