Title:
  ML2 mechanism driver DVR PortContext info incomplete/inconsistent

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

Bug description:
  While extending the existing ML2 port binding unit tests to cover DVR
  distributed port binding (bug 1453943), I ran into a number of issues
  where the PortContext passed to ML2 mechanism drivers does not provide
  the information needed for distributed ports or provides it
  inconsistently. This is likely to prevent existing mechanism drivers
  for ToR switches from working with DVR ports, and tests have
  reportedly shown this to be the case.

  When DVR was introduced, the host, original_host, status, and
  original_status attributes were added to PortContext to provide
  drivers with the host-specific details of distributed (or normal)
  ports. But the current and previous port dictionary attributes also
  contain some host-specific information, such as the VIF type, for
  distributed ports. New attributes need to be added for host-specific
  current and previous VIF type and details, and the current and
  previous port dictionaries should contain only the host-independent
  information that is returned from REST operations.

  Also, the existing original_status and original_host PortContext
  attributes should return None when in the context of create or delete
  operations, and original_host should reflect the host for which a
  distributed port operation is being performed.
