Additional Deployment Changes

[dbarkowsky]

Summary

Changes

• Bumped up the frontend memory limit. Combined with the 80% usage-based scaling, it was max scaling to 4/4 pods all the time. Will have to monitor.
• Some properties of the stateful sets are apparently immutable, so one of the previous changes required dropping the sets then immediately recreating them. It seems like --cascade=orphan causes the pods to keep running, so the disruption in the PLG stack is seconds short. Probably not needed every deployment, but it eliminates a lot of conflicts if it comes up again.
• Had to add additional permissions for role-based access controls, which is related to the previous changes with the Prometheus service account.

Testing

I've tested what I could by running things from the CLI. Suspect everything will work, but will monitor workflow runs.
