Thought we already had an epic or some issues for this work, but couldn’t find them. Figured I’d just go ahead and try breaking it down really quick and then start in on it.

Merged the schema change ( mozilla/nimbus-shared#179 ) adding the isRollout property after feedback. Next step in the process ( mozilla/nimbus-shared#183 ) is to create a nimbus-shared release with the changes and then file QA tickets.
