set up docker/jenkins instance on wonka to do CI builds of RPM

To enable building the RPM via CI builds, in response to new devstudio builds, need a Jenkins server on which we can run rpmbuild and mock.

I have root access to wonka and it has TONS of space, so that seems a viable place to host this until we can get eng-ops to support Fedora24 or RHEL7 w/ EPEL.
