ceph: periodically send perf metrics to MDSes
This will send the caps/read/write/metadata metrics to any available MDS once per second, which will be the same as the userland client. It will skip the MDS sessions which don't support the metric collection, as the MDSs will close socket connections when they get an unknown type message. We can disable the metric sending via the disable_send_metrics module parameter.
