Bug description:
  There is currently no method built into Nova to keep connections from
  various components into RabbitMQ alive.  As a result, placing a
  stateful firewall (such as a Cisco ASA) between the connection
  can/does result in idle connections being terminated without either
  endpoint being aware.

  This issue can be mitigated a few different ways:

  1. Connections to RabbitMQ set socket options to enable TCP
  keepalives.

  2. Rabbit has heartbeat functionality.  If the client requests
  heartbeats on connection, rabbit server will regularly send messages
  to each connections with the expectation of a response.

  3. Other?
