Doc Text:
Previously, there was no command to retrieve the status and the various parameters of async tasks for one more volumes. The 'volume status [all]' command was used for this purpose and it additionally displayed the status, PIDs, port number of the bricks, self heal daemon and the NFS server. With this update, the 'tasks' option is introduced to the 'volume status' command to retrieve status of async tasks for one or more volumes.

    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.
