[WIP]: Create a json-rpc lib (#121)

* Create the basics for a json-rpc client lib

This commit adds a trait with all possible json-rpc methods exposed by
florestad, as well as all the types returned by it.

Specific implementations should use some networking lib like jsonrpc or
reqwest to actually implement the trait methods and make a concrete
implementation.

* add a concrete implementation with reqwest

* add integration tests to the cli lib

* document all rpcs and data they return

* use the cli lib inside the rpc cli client
