Unify env_details file

Is your feature request related to a problem? Please describe.

I'm always frustrated when I see the same things named differently, especially when I am trying to do it often and trying to do it fast.

Describe the solution you'd like

It would be nice to make it more standard: for main services it has "RPC", "Endpoint" or "Address" names for the same things. A control port is named "GRPC address" or "Control gRPC endpoint" depending on the service. Metrics are either "Metrics address" or "Prometheus address".

Describe alternatives you've considered

Nothing was considered.
