glusterd/rebalance: Display run-time of rebalance process
Added run-time value field to cli output of rebalance/remove-brick. A new cluster/distribute boolean option rebalance-stats when set to ON, time taken for migration of each file is logged. With rebalance-stats OFF (default), rebalance logs will only have entries showing time spent in each directory.
