Adjusting Katello test jobs

I will be adjusting Katello test jobs to try to get better throughput
through our CI system and in preparation to move to the Jenkins PIpeline
plugin once Dominic is able to install it. For a while, please be mindful
of any strangeness or breakages and report them to me for investigation.
