Adding new RPCs

Adding new RPCs to any of the server roles is currently a little involved. Here's a list of what you'll need to modify:

1. Add RPC definitions to proto files. Either in the api repo (for frontend) or here in proto/internal (for history/matching).
2. Update go.temporal.io/api to pick up the new generated files (for frontend) or generate them here with make proto (for history/matching).
3. Add metric scope defs for client-side metrics to common/metrics/defs.go (this is going away soon).
4. make go-generate to generate wrappers in client.
5. For frontend: add definitions to service/frontend/dcRedirectionHandler.go. (In the future hopefully we can make this generated or use interceptors.)
6. Add your new methods to service/<service>/configs/quotas.go.
7. Finally implement your new methods in the RPC handler.
