Dustin 404fadc68a jenkins: Run Jenkins in Kubernetes 
Running Jenkins in Kubernetes is relatively straightforward.  The
Kubernetes plugin automatically discovers all the connection and
authentication configuration, so a `kubeconfig` file is no longer
necessary.  I did set the *Jenkins tunnel* option, though, so that
agents will connect directly to the Jenkins JNLP port instead of going
through the ingress controller.

Jobs now run in pods in the *jenkins-job* namespace instead of the
*jenkins* namespace.  The latter is now where the Jenkins controller
runs, and the controller should not have permission to modify its own
resources.
