As we discussed before, we wanted some way for the user to recover from a FAILED metadata status. The state we want to get it into is RETRY since we have logic for those cases in the RollupRunner and RollupMetadataService. If we want to use the _start API as the mechanism for users retrying failed metadata cases, then we can add the logic here to update from FAILED -> RETRY.

This can be made in a separate PR, we'll just want to make sure that there is some mechanism for triggering a retry from the user. We can also review the retry workflow for rollup in general at that time, such as changing _stop to not set to STOPPED if it's in FAILED state as well.
