The image used for the tests is just treated as a blob, no guests
are booted using it so to speed up the tests when using slow
storage by switching to using cirros image. The cirros image is ~20
times smaller than the bionic one.
There was a race before a block_until_all_units_idle() where it
could blast through the check before it started removing the relation.
This ensures that it waits until something happens and then waits for it
to finish.
The test won't pass on serverstack due to the snapd taking a copy of the
/mnt/vdb info at boot time and thus not being able to umount it is root
without also running through all of the procs and checking if they also
have it mounted. Thus, this just disables the test on focal and newer.
When testing with TLS there is a chance the deployment will appear
done and idle prior to ceph-radosgw and Keystone have updated the
service catalog. Retry the test in this circumstance.
Increase wait attempts for availability of volume created from image
in CephRBDMirrorTest. This is taking longer as of Nautilus due to
switch to using juju storage backed by undercloud cinder taking
longer than prior method of directory-backed OSD devices.
