M. J. Fromberger 1995ef2572 rpc: Strip down the base RPC client interface. (#6971)
* rpc: Strip down the base RPC client interface.

Prior to this change, the RPC client interface requires implementing the entire
Service interface, but most of the methods of Service are not needed by the
concrete clients. Dissociate the Client interface from the Service interface.

- Extract only those methods of Service that are necessary to make the existing
  clients work.

- Update the clients to combine Start/Onstart and Stop/OnStop. This does not
  change what the clients do to start or stop. Only the websocket clients make
  use of this functionality anyway.

  The websocket implementation uses some plumbing from the BaseService helper.
  We should be able to excising that entirely, but the current interface
  dependencies among the clients would require a much larger change, and one
  that leaks into other (non-RPC) packages.

  As a less-invasive intermediate step, preserve the existing client behaviour
  (and tests) by extracting the necessary subset of the BaseService
  functionality to an analogous RunState helper for clients. I plan to obsolete
  that type in a future PR, but for now this makes a useful waypoint.

Related:
- Clean up client implementations.
- Update mocks.

package mock
/*
package mock returns a Client implementation that
accepts various (mock) implementations of the various methods.
This implementation is useful for using in tests, when you don't
need a real server, but want a high-level of control about
the server response you want to mock (eg. error handling),
or if you just want to record the calls to verify in your tests.
For real clients, you probably want the "http" package. If you
want to directly call a tendermint node in process, you can use the
"local" package.
