Raise the file limit on the RabbitMQ cluster

Browse source 
RabbitMQ recommends[0] that the open file descriptor limit be set to a
minimum of 50K. It recommends that the maximum number of open
connections be multiplied by 2 and added to the total number of queues.
Finally, it suggests that 500K isn't an unreasonable setting. This sets
the default to 500K and makes the value configurable.
