List and stop long running commands

See this idea on ideas.ibm.com

Some Spectrum Scale commands can take a long time to run, such as mmapplypolicy, mmrestripefs, mmecheckquota. These might be run manually, or started by cron a batch system, or a callback. But sometimes, once started, there is a need to stop the command before it is finished. Control-C might stop it (not clear from docs) but waiters continue, and sometimes the fsmanager is continuing the operation. Besides, it isn't always clear where a command is running, if you wanted to control-c it (or use sigintr).

So there needs to be a documented command for an end user to see what long-running commands are running, what there state is (running, stopping, etc.), and some way to request one of these commands to stop "as soon as safely possible".

If this could be made even more general: maybe allow pause/resume of a command, altering the QoS and set of helper nodes being used, provide some measure of performance impact of the command, and dare I say it - an estimate of completion time.
