NSB sync: clean-up draft IPC implementation (part 1)

  The existing implementation of IPC is not finished and isn't used
by any of the VNFs/TG implementation. It is used in the code but does
nothing from functionality perspective.
  New syncronization mechanism is going to be implemented by using
different approach than it was designed before. Thus, the current
IPC mechanism is not going to be re-used. So, removing it.
  The IPC consumer/producer implementation is left as it may be
required for other purposes.

- Remove SampleVNF MQ consumer class
- Remove IterationIPC MQ producer for VNF control messages
- Remove MQ producer from SampleVNFTrafficGen class
- Remove TrafficGeneratorProducer class
- Remove IterationIPC runner
- Remove unused task_id form VNF Generic initialization as it is not
  required for synchronization of VNFs/TGs anymore.
- Fix UT
