stat enhancements
* dht to send 'setxattr' to all subvolumes in the layout * server dumps info on total bytes read/written for 'trusted.io.stat.dump' key * server dumps all the mount point IP for 'trusted.list.mount.point' key. * io-stats dumps latency information only if measured Signed-off-by: Amar Tumballi <amar@gluster.com> Signed-off-by: Vijay Bellur <vijay@dev.gluster.com> BUG: 1701 (better statistics gathering in glusterd) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=1701
