mds, client: only send the metrices supported by MDSes

For the old ceph clusters the clients won't send any metrics to
them as default unless they have backported this commit, but there
has one option 'client_collect_and_send_global_metrics' still could
be used to enable it manually.

This will fix the crash bug when upgrading from old ceph clusters,
which will crash the MDSes once they receive unknown metrics.
