Description
Client already tracks cumulative read/write/metadata latencies. However, average latencies are much more useful to the user.
Start tracking average latencies and forward to the MDS for displaying in `perf stats` command (and `cephfs-top` utility).
(kclient also needs to start sending these metrics).
