Title:
  Cells connecting pool tracking

Status in OpenStack Compute (nova):
  Fix Released
Status in OpenStack Compute (nova) juno series:
  New

Bug description:
  Cells has a rpc driver for inter-cell communication.  A
  oslo.messaging.Transport is created for each inter-cell message.

  In previous versions of oslo.messaging, connection pool references
  were maintained within the RabbitMQ driver abstraction in
  oslo.messaging.  As of oslo.messaging commit
  f3370da11a867bae287d7f549a671811e8b399ef, the application must
  maintain a single reference to Transport or references to the
  connection pool will be lost.

  The net effect of this is that cells constructs a new broker
  connection pool  (and a connection) on every message sent between
  cells.  This is leaking references to connections.
