Mirroring policy for RabbitMQ

The commit adds a new mirroring policy for RabbitMQ that ensures
that:
	* All queues except for amq.* have 1 additional mirror
	* TTL for messages is set to 120 seconds
	* Priority set to 2 in order to prevail

Since RabbitMQ policies do not combine, the winning policy must contain
all the options from other policies in order to have a complete effect
on the queues and exchanges.
