librbd: support compression allocation hints to the OSD

A new "rbd_compression_hint" configuration option can be applied
globally, at the pool level, or to individual images to send
the associated compression allocation hint to the OSD on write
operations.

Fixes: https://tracker.ceph.com/issues/42097

(cherry picked from commit 200fc5b2f24859109a79002e30927d457971b939)
