fixes:

Fixes an issue where RabbitMQ consumes a large amount of CPU, particularly
on multi-core systems. The default RabbitMQ tuning assumes that RabbitMQ
is running on a dedicated host, which is the opposite of a typical Kolla
Ansible container setup. For more details on tuning RabbitMQ in your
environment, please see: https://www.rabbitmq.com/runtime.html#busy-waiting

upgrade:

Modifies the default value of ``rabbitmq_server_additional_erl_args`` from
an empty string to ``+S 2:2 +sbwt none +sbwtdcpu none +sbwtdio none``.
