Workflows can now be cancelled when not started or enqueued.
Also displaying the stop option when selecting all.
We got the case of a client that did an infinite loop. So he had a lot
of workflows to stop. Supporting select all would have avoid him to wait
for 4 hours so we process the runs throttled. This is not something that
is supposed to happen often so I did not see the point of refactoring
the endpoint. But I wanted the users to have this option just in case
