gRPC between OPAL client and server

[hongbo-miao]

Just an idea.
gRPC (over HTTP/2) might be a better option between OPAL client and server communication than current WebSocket (HTTP/1.1).
gRPC is quite common in cloud native world. 😊

Hi @hongbo-miao !
So good to hear from you.

GRPC is notoriously bad in over the internet connection. It's more than fine within your VPC but once you add some routing in between and a little latency it fails miserably.

We can consider adding a GRPC option, in addition to Websocket. If you (or anyone else) would like to contribute that, I'd be more than happy to provide guidance.
