This reverts commit 8707919facffcb9bf8d632098bc9ffe23d5276ab.
Merge branch 'master' into jira/PJSM-185

Conflicts:
	sampler-repo-webapp/src/main/webapp/opennms-setup.karaf
Fixed mismatch in name of vm:// broker for minion. Separated the
features:install of the "activemq" feature from the features that
rely on activemq to further ensure that ActiveMQ starts before
features that rely on it.
Split ActiveMQ configs into their own features. Changed ActiveMQ to only
accept connections from TCP 61616.
Changed default Karaf SSH ports to start at 8201 to avoid conflicts
with standalone Karaf instances and OpenNMS. Changed the init scripts
so that they call smnnepo-setup.karaf to configure the root instance
and create clones for each subinstance, then call smnnepo-setup.karaf
in each subinstance to configure and install the desired features for
that instance.
Merge branch 'master' into jira/PJSM-185
Minor cleanup in init scripts, setup script, and POM.
Updated sampler configs to use port 61716 for ActiveMQ on the Minion brokers
so that it doesn't conflict with the OpenNMS broker running on port 61616.
Updated Camel to 2.13.2.
Tweaked a couple of classes used in unit tests.
