Since the default of `osd_objectstore` has changed as of 3.2, some
deployments might have a mix of filestore and bluestore OSDs on a same
node. In some specific cases, there's a possibility that a filestore OSD
shares a journal/db device with a bluestore OSD. We shouldn't try to
redeploy in this context because ceph-volume will complain. (either
because in lvm batch you can't pass partition or about gpt header).
The safest option is to skip the migration on the node when such a mix
is detected or force all osds including those already using bluestore
(option `force_filestore_to_bluestore=True` has to be passed as an extra var).
If all OSDs are using filestore, then they will be migrated to
bluestore.

If the filestore configuration was using a dedicated journal with either
a partition or a LV/VG then we need to reuse this for bluestore DB.
When filestore is using a raw devices then we shouldn't destroy
everything (data + journal) but only data otherwise the journal
partition won't exist anymore.

This commit adds a task to ensure device mappers are well closed when
lvm batch scenario is used.
Otherwise, OSDs can't be redeployed given that devices that are rejected
by ceph-volume because they are locked.

dm only when using lvm batch scenario.
