Description

We currently create a dedicated RpcSystem for each test, meaning that we go through the whole cycle of extracting the rpc-akka jar and creating a new classloader.

For testing purposes we can re-use the same RpcSystem, which will alleviate FLINK-18356 and maybe speed up some test or two.
