What this PR does / why we need it:

Feast currently supports running the Registry API server in either rest or grpc mode i.e. two mutually exclusive modes. This PR will allow user to run both gRPC and REST APIs at the same time. Opt-in behavior for multi-mode. By default, only gRPC is enabled. User can explicitly enable REST via flags.

  • feast serve_registry (run only grpc)
  • feast serve_registry --no-grpc --rest-api (run only rest)
  • feast serve_registry --rest-api (run both grpc and rest)

The REST server listens on port 6572 by default. User can also override the rest port using --rest-port option.

# feast serve_registry --help
Usage: feast serve_registry [OPTIONS]

  Start Feast Registry server (gRPC by default, REST opt-in).

Options:
  -p, --port INTEGER   Specify a port for the server
  --rest-port INTEGER  Specify a port for the REST API server (if enabled).
                       [default: 6572]
  -k, --key TEXT       path to TLS certificate private key. You need to pass
                       --cert as well to start server in TLS mode
  -c, --cert TEXT      path to TLS certificate public key. You need to pass
                       --key as well to start server in TLS mode
  --grpc / --no-grpc   Start a gRPC Registry Server. Enabled by default.
                       [default: grpc]
  -r, --rest-api       Start a REST API Registry Server
  --help               Show this message and exit.
