/**
* This test case is used to load test store and forwarding between brokers. It sets up
* 10 brokers to which have a chain of queues which this test consumes and produces to.
*
* If the network bridges gets stuck at any point subsequent queues will not get messages. This test
* samples the production and consumption stats every second and if the flow of messages
* get stuck then this tast fails. The test monitors the flow of messages for 1 min.
