Passing the strict lint checks requires a number of backwards-
incompatible changes:
- Rename the NodePrivileged service to NodePrivilegedService.
This is only used in CLI tooling, which are upgraded at the same
time as the server binary.
- The Publicrpc service was renamed to PublicRPCService.
- The EmitterChain type is renamed to ChainID.
- The default value for the ChainID type is renamed to
CHAIN_ID_UNSPECIFIED. This value wasn't referenced anywhere.
- The response and request types for GetLastHeartbeats were updated
to match the rpc method name.
