Allow Curators to disable Artisans to schedule hourly worlflows

[mestevez1]

I manage a server with 200 + Artisans. Some of them tend to abuse the Scheduler by having workflows running every hour or every x hours. This can penalize other users creating big queues thought the day. Currently I monitor the queue and schedule often and then contact these individuals to better accommodate their needs.

Having the possibility to disable hourly workflows, or enable to only specific users, would help a lot to deter the abusers.

Thanks,
