Description

Flink-runtime code does not only interact with akka-reliant code through the RpcService interface, but also through various static helper methods.

A new RpcSystem interface shall be added that serves both as a factory for RpcService and a facade for these utilities.
Through this interface we will later load the AkkaRpcSystem as a plugin.
