chore(server): setup ServerProto pieces to be deprecated

Browse Source 
- Adds a `server-proto` feature that is added to default features.
- If `server-proto` feature is not enabled, pieces that will eventually
  be deprecated and optional will be tagged deprecated, but with a note
  about the missing `server-proto` feature.
