addons: Add better alerting rules to Prometheus manifests

Browse Source 
* Adapt the coreos/prometheus-operator alerting rules for Typhoon,

* Add controller manager and scheduler shim services to let
prometheus discover them via service endpoints
* Fix several alert rules to use service endpoint discovery
* A few rules still don't do much, but they default to green
