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).

Xiubo suggested that the client also sends min/max and stddev.
