glusterd: Add info on op-version for clients in vol status output
Currently the `gluster volume status <VOLNAME|all> clients` command gives us the following information on clients: 1. Brick name 2. Client count for each brick 3. hostname:port for each client 4. Bytes read and written for each client There is no information regarding op-version for each client. This patch adds that to the output.
