Initial Commit of Console Load Test with Feeder
(PE-4769) Modify the gatling agent run to simulate multiple agents

This commit adds the Puppet Enterprise gatling load test simulation with
a feeder functionality. This means that when the test is run, not only
does it simulate load of X number of nodes, but it will add that number
of nodes into the console for UI testing.
