Description of problem:
With https://github.com/ceph/ceph/pull/43546 merged, cephfs-mirror can make use the snapdiff api (via readdir_diff) to efficiently traverse the directory tree between two snapshots.

This should hugely improve performance when only a handful of files have changed between two consecutive snapshots.
