Title:
  Quantum Manager needs synchronization

Status in OpenStack Quantum (virtual network service):
  Fix Released

Bug description:
  Quantum server loads plugin via QuantumManager class in different threads.
  When there are lots of messages in MQ, amount of threads in high and duplicating log messages could be seen that indicate that core plugins and service plugins were loaded multiple times.

  QuantumManager singleton needs to be either synchronized or
  initialized at server start.
