Title:
  Lack of singleton guarantee

Status in OpenStack Neutron (virtual network service):
  Won't Fix

Bug description:
  The current neutron's code require a singleton in some case, e.g., some class requires to be singleton.
  However, there is no mechanism to guarantee this.
  For example, in neutron.manager.NeutronManager class, the comments say "The caller should make sure that NeutronManager is a singleton".
  This kind of implementation is not only unsafe to assure the protection, but also make the caller to handler unnecessary efforts.
