[rpc] crate follow-ups

[xla]

As leftovers from #338 we need to address to main points

• crate documentation chore: move net2 dependency out of tendermint crate #338 (comment)
• a satisfying solution to the now public serialisers: chore: move net2 dependency out of tendermint crate #338 (comment)
• potentially make only endpoints available: Feature guard the networking stuff #289 (comment)

It seems keeping the endpoint data types inside tendermint crate, can also help keeping the serializers private.
feature guarding is good too.

@yihuang from your point of view and keeping the serializer helper methods aside, are their other good reasons to keep the rpc endpoints (or the whole module) inside the tendermint crate?

I don't have other reasons for that, I think feature guarding is good too ;D

Given all the recent serialization work, can we close this @thanethomson @greg-szabo ?
