Scheduled content sets for content sync

[#1]

Request for Feature Enhancement (RFE) Summary:	Scheduled content sets for content sync
Use-case:	We have more than 60 sites on our AEM instance (and growing). There are days where we use to create content packages to sync all these sites content from Prod to lower enviroments. We were very happy to see the feature "Content sets", which made sync easy. Now we have to manually run sets for the sync process every two weeks.
Current/Experienced Behavior:	Executing the Content sets manually
Improved/Expected Behavior:	Ability to schedule the executing of content sets
