>             Fix For: 1.5.0
> As part of refactoring of the cluster management, we can introduce a new RPC abstraction
on top of our Akka-based distributed coordination.
> It should address the following issues:
>   - Add type safety to the sender and receiver of messages. We want proper types methods
to be called, rather than haveing generic message types and pattern matching everywhere. This
is similar to typed actors.
>   - Make the message receivers testable without involving actors, i.e. the methods should
be callable directly. When used with other component, the receiver will be wrapped in an actor
that calls the methods based on received messages.
>   - We want to keep the paradigm of single-threaded execution per "actor"
> There is some basic code layout in the following branch and commit:
