Move protos to separate repo?

[masomel]

Maintaining the protobufs in a separate repo would make it easier to ensure that both CONIKS implementations use compatible protobuf messages. Any changes to the protobufs could then be easily propagated to both implementations. This repo would contain the compiled protobufs for each supported language, which can then be imported by each implementation.

Yeah, I think so, too. I also think that we can adopt protobufs into our storage backend hook. It would replace the Deserialize and Serialize problem we're facing.

That's an interesting point, this is definitely something we should consider.
