Rabbit logs

See: https://trello.com/c/HbBXu7vD/60-3-monitoring-check-rabbit-logs-to-detect-issues-not-reflected-in-service-list-python and https://github.com/rcbops/openstack-probes/issues/5
Nit-picking here, but would it make sense to have a separate arg for host/port?  I tried using some of these methods manually and it didn't really work.  Being able to run configure() without the optparse stuff may come in handy at some point in the future.
