Other ways to terminate a (re)flow?

[hjoliver]

If you trigger a reflow and then leave it alone, it could:

• peter out naturally (e.g. you triggered a branch of the graph that terminates after a while)
• or keep going indefinitely
• or catch up and merge with another flow

Otherwise, cylc stop --flow=LABEL will stop the targeted flow from spawning on any further.

Do we need other ways of stopping a reflow? E.g. stop at a given,

• cycle point?
• list of task IDs?
• wall clock time?

Do we need other ways of stopping a reflow?

My guess would be that we probably don't "need" it, however, it would be very nice, and, hopefully not that difficult to add flow_label to the existing stop/hold interfaces.

In particular I think this one might get a bit of use:

cylc stop <flow> <point> --flow <label>

See #3745 comments on hold as well.

cylc stop --flow
