When a directory is removed from mirroring, the persisted directory
stats need to be removed. This patch handles the cleanup.
Omap keys must not be removed when mirrored directories are reshuffled
across cephfs-mirror daemons. The mgr release notify now carries a
purging flag (set only during permanent removal, not reshuffle), and
the daemon removes persisted stats only when purging is true. On
reshuffle with an in-progress sync, clear live current_syncing_snap
state and persist idle metrics so the acquiring daemon does not inherit
stale syncing omap entries.
