Introducing the new override rabbitmq_memory_high_watermark

openstack/openstack-ansible-rabbitmq_server

Code Issues Proposed changes

The override rabbitmq_memory_high_watermark can be used to
alter the overall memory consumption of rabbitMQ and more
importantly define when the garbage collection (gc) is happening.
The old default value of 0.4 can lead up to 80% memory usage
during gc which can lead to OOM scenarios.
The new default value is set to 0.2, lowering the maximum memory
usage to 40%
