As reported in
https://github.com/ceph/ceph-ansible/issues/1403 when devices are held
by lvm and `osd_auto_discovery` is set to true, it's not enough to check
for a partition count = 0 since Ansible does not report.
This patch also looks for 'holders' which in a case of lvm corresponds
to the name of the pv. Now we also look for holders = 0.
Fixes: #1403

Even for dmcrypt we need to check the "devices" status and
"raw_journal_devices" as well so we can fix them if there is something
wrong with them.

This allows us to test devices set with persistent naming such as
/dev/disk/by-*
When registering devices we can use persisent (/dev/disk/by-*) or
non-persistent (/dev/sd*). Both declarations are supported by
ceph-ansible. There was just two tasks that were not compatible with
this. Since we support using partitions directly we need to test that
because the device activation will be different. To test if the device
is a partition we use a regular expression which wasn't compatible with
the persistent device naming format (/dev/disk/by-*).
This commit solves this issue by reading the path of the symlink since
devices like /dev/disk/by-* are symlinks to devices like /dev/sd*
