Currrently, 'gluster v quota <VOLNAME> list' command rounds off the
available space and shows it to the user. Now, 'gluster v quota
<VOLNAME> list --xml' command is modified to show the exact available
space in bytes.

> Currently the tier feature piggy backs off the rebalance command
> syntax to obtain status and this is clumsy. Introduce a new
> tier command that can do tier specific operations, starting
> with volume status to display counters.

> Old commands:
> gluster volume attach-tier <vol> [replica count] {bricklist..}
> gluster volume detach-tier <vol> {start|stop|commit}

> New commands:
> gluster volume tier <vol> attach [replica count] {bricklist} |
>                           detach {start|stop|commit} |

There is a problem in current CLI framework
CLI holds the lock when processing command.
When processing quota list command, below sequence of steps executed in the
same thread and causing deadlock

1) CLI holds the lock
2) Send rpc_clnt_submit request to quotad for quota usage
3) If quotad is down, rpc_clnt_submit invokes cbk function with error
4) cbk function cli_quotad_getlimit_cbk tries to hold lock to broadcast
   the results and hangs, because same thread has already holding the lock

This patch fixes the problem by creating seperate thread for
broadcasting the result
