* Elasticsearch: Add frozen indices support for alerting

This adds a check to see if plugin route URL is empty, and in such case 
does not modify request schema and host of the request to be proxied.
This behavior is now the same as in the plugin proxy.

kuberentes (and Im sure other orchastrators does as well) support two
kind of checks. readiness checks and liveness checks. Grafanas current
`/api/health` endpoint requires database access which might not
always be required for the instance to be considered active.
