Add prov warning to primary/secondary commands 

Warn the administrator if there are active provisioning jobs while
adjusting the current primary node. This is the simplest, cleanest
solution to #69 without trying to implement any hacks or blocking
operations. The administrator can then decide to revert the action
if needed, or will at least know how many jobs are running/queued and
may need to be cancelled.
