gRPC + Protocol Buffers

[tiero]

On the line of this kyuupichan/electrumx#993 would you be interested in potential contributions to take full advantage of HTTP2 streaming features and self-generating stubs with grpc/protobuf ?
Thanks

a new binary target here

Do you mean to specify multiple binaries, so it would be compiled to two different executables one with the JSONRPC and one with gRPC one?

Why not add in the same binary the gRPC interface exposed on a different port, where maybe the user could opt-in via a command?

Sounds good.

Would be nice if it could work with both at the same time.
