glusterd: bring in feature to use syncop for mgmt ops
* new sycnop routines added to mgmt program * one should not use 'glusterd_op_begin()', instead can use the synctask framework, 'glusterd_op_begin_synctask()' * currently using for below operations: 'volume start', 'volume rebalance', 'volume quota', 'volume replace-brick' and 'volume add-brick' Change-Id: I0bee76d06790d5c5bb5db15d443b44af0e21f1c0 BUG: 762935 Signed-off-by: Amar Tumballi <amar@gluster.com> Reviewed-on: http://review.gluster.com/479 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>
