AURORA-14: CI tests broken due to missing egg

Until Apache Mesos publishes the egg or we come up with a work around
commenting out the tests which depend on the the mesos python client.

This patch also adds a script for the CI tests to capture this information
and make it available for others to use.

I have linked MESOS-684 (deploying build artifacts) to AURORA-14 and have
started looking into a better approach to building this egg or making it
publicly available.

Testing Done:
Ran new jenkins build.sh script included with this patch and python tests passed with
