cli,glusterd: Implement 'volume status tasks'
oVirt's Gluster Integration needs an inexpensive command that can be executed every 10 seconds to monitor async tasks and their parameters, for all volumes. The solution involves adding a 'tasks' sub-command to 'volume status' to fetch only the async task IDs, type and other relevant parameters. Only the originator glusterd participates in this command as all the information needed is available on all the nodes. This is to make the command suitable for being executed every 10 seconds.
