Fix failing JMX tests (#426)

* Extended agent run time from 2 to 5 minutes and set metrics_collection_interval to 60 seconds to better capture infrequent metrics (like jvm.gc.collections.elapsed and jvm.gc.collections.count) Some tests were failing because the average value of metrics fell slightly outside of the bounds (+/- 10%). I * Added java commands to enable the mbean registry to properly expose tomcat metrics * Upped error percentage to 15% from 10%
