[pve-devel] [RFC manager 5/9] partially fix #2285: api: ceph: create osd: allow using partitions

Note that this does not only allow partitions to be used, but for DB
and WAL disks, one more type of disk, that wasn't allowed before.
Namely, GPT-partitioned disks with any partitions detected as used.
The reason is get_disks' behavior:
  * Without $include_partitions=1, the disk will have the same usage
    as it's first used partition, and thus wasn't allowed. (Except in
    the case that usage was LVM, where the check was bypassed, but
    luckily OSD creation just failed later because no Ceph volume
    group would be detected).
  * With $include_partitions=1, the disk will have usage 'partitions'
    and thus be allowed.

RFC, because of the weird situation with the DB/WAL disks...

Dependency bump for pve-storage is needed to actually make it work,
because previously it wasn't supported to pass along partitions as
elements of the first argument.
