Remove scope suffixes for RPC communication

[pLeminoq]

Currently the AbstractControllerServer and AbstractRemoteClient add a control to the RPCServer/RPCClient scopes.

Line 277 in 93af28e

this.rpcClient = factory.createRPCClient(ScopeProcessor.concat(scope, AbstractControllerServer.SCOPE_SUFFIX_CONTROL), communicatorConfig);

This can be removed as the mqtt implementation adds the suffix /rpc to the scope anyway.
