ceph_volume: fix multiple db/wal devices
When using the lvm batch ceph-volume subcommand with dedicated devices
for bluestore (db/wal) then the list of devices is convert to a string
instead of being extended via an iterable.
This was working with only one dedicated device but starting with more
then the ceph_volume module fails.

ceph-volume lvm batch: error: Unable to proceed with non-existing device: /dev/nvme0n1 /dev/nvme1n1
So the dedicated device list is considered as a single string.
This commit also adds the block_db_devices and wal_devices documentation
to the ceph_volume module.
