cli: Extend "volume status" with statedump info
This patch enhances and extends the "volume status" command with information obtained from the statedump of the bricks of volumes. Adds new status types : clients, inode, fd, mem, callpool The new syntax of "volume status" is, #gluster volume status [all|{<volname> [<brickname>] [misc-details|clients|inode|fd|mem|callpool]}] Change-Id: I8d019718465bbc3de727653a839de7238f45da5c BUG: 765495 Signed-off-by: Kaushal M <kaushal@redhat.com> Reviewed-on: http://review.gluster.com/2637 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Krishnan Parthasarathi <kp@gluster.com>
