helm-toolkit prometheus service annotation clean up

This adds checks for the fields in the service annotations for
prometheus, similar to the checks made for the pod annotations.
It also moves prometheus annotations under a prometheus: key
under a top-level monitoring tree to allow for other monitoring
mechanisms independent of the endpoints tree
