Steven Fitzpatrick cdd0f33d0c Revert "Prometheus: Render Rules as Templates" 
This reverts commit fb7fc87d23.

I first submitted that as a way to add dynamic capability to the
prometheus rules (they infamously don't support ENV variable
substitution there). However this be done easily with another solution,
and would clean up the prometheus chart values significantly.
