Refactoring prometheus metrics and labels (#2375)

Browse Source 
This change mainly fixes few things around router and executor
exposed metrices.
1. We are trying to follow standard in metric names.
2. Lables such as namespace are colliding with kube-prometheus standards
so they are getting relabled to exported_namespace. Added function prefix
to resolve this.
