tools/cephfs_mirror: Adds capability to persist metrics
Adds the capability to persist mirroring metrics.
The metrics are persisted in the omap of the cephfs-mirror
object. Metrics are persisted asynchronously.
Each mirrored directory path stores the corresponding
metrics as the value of a unique omap key representing
the mirrored directory. The omap key is as below.
sync_stat/<fsname>/<peer_uuid>/<mirrored_dir_path>
