Previously (when python 2 was supported) we introduced some specific
exception management to detect connections issues when a rabbitmq
cluster node disappearing.
The original issue was that a ConnectionRefusedError is thrown and not
managed by oslo.messaging to detect heartbeat issue and call ensure_connection
for switching the connection destination (cluster node).
`ConnectionRefusedError` is only a python 3 exception [2].
Now that we only support python 3 we don't need to continue to
wrap/emulate this kind of exceptions (ConnectionRefusedError) [2] and
so we can drop the python 2 compatibility code to only support python 3 code.
