> The {{NetworkEnvironment}} communicates with the outside world ({{TaskManager}} and {{JobManager}}) via {{ActorGateways}}. This bakes in the dependency on actors. 
> In terms of modularization and an improved abstraction (especially wrt Flip-6) I propose to replace the {{ActorGateways}} by interfaces which exposes the required methods. The current implementation would then simply wrap the method calls in messages and send them via the {{ActorGateway}} to the recipient.
> In Flip-6 the {{JobMaster}} and the {{TaskExecutor}} could simply implement these interfaces as part of their RPC contract.
