the backend can use the new "fixed" collection_list method,

ceph-volume: retry when acquiring lock fails
When preaparing the osd device with --mkfs, the ceph-osd binary tries to
acquire an exclusive lock on the device (soon to become an OSD).
Unfortunately, when running in containers, we have seen cases where
there is a race between ceph-osd and systemd-udevd to acquire a lock on
the device. Sometimes systemd-udevd gets the lock and releases it soon
so that the ceph-osd gets sometimes the lock is still held and because
ceph-osd uses LOCK_NB the command fails.
This commit retries if the lock cannot be acquired, up to 5 times for 5
seconds, this should be more than enough to acquire the lock and
proceed with the OSD mkfs.
Unfortunately, this is so transient that we cannot lock earlier from c-v,
this won't do anything.

mgr/volumes: maintain per subvolume trash directory
PR https://github.com/ceph/ceph/pull/36472 introduces changes
that disallow nested nested snapshots in a subtree (subvolume)
and renames across subvolumes. This effect asynchronous purge
in mgr/volumes as subvolume are moved to a trash directory for
asynchronous deletion by purge threads.
To workaround this, start maintaining a subvolume specific
trash directory. Use the trash directory as an index to the
subvolume specific trash directory entry.
This changes subvolume deletion logic which currently relies
on `--retain-snapshots` flag to decide if the subvolume user
directory should get purged or the subvolume base directory
itself. Deleting a subvolume moves the user facing directory
to its specific trash directory. Purge threads take care of
deleting user facing directories (in trash) and the subvolume
base directory if required (when certain conditions are met).
mgr/volumes: Use snapshot root directory attrs when creating clone root
If a subvolumes mode or uid/gid values are changed post a snapshot,
and a clone of a snapshot prior to the change is initiated, the clone
inherits the current source subvolumes attributes, rather than the
snapshots attributes.
Fixing this by using the snapshots subvolume root attributes to create
the clone subvolumes root.
Following attributes are picked from the source subvolume snapshot:
- uid, gid, mode, data pool, pool namespace, quota
