Public bug reported:

It is undesirable to keep many TCP connections open at the same time
because doing so consumes system resources and makes it more difficult
to scale.

E.g OVS agent creates 15 long-lived connections to rabbitmq from scratch

Comparing to Nova which uses 3 connections
https://paste.opendev.org/show/bTeFYCTEVX4Hx3YHwJi2/

Agent creates separate topic/RPC server for each resource, like neutron-
vo-Network-1.1, neutron-vo-SecurityGroup-1.2, neutron-vo-Port-1.5 and so
on.

We could combine these calls into couple RPC servers and reduce
connection number, oslo.messaging supports connection pool, which could
be configured via config, so it manages connections dynamically.
