Charts do not work on OpenShift

[kfeinauer]

Our containers require root privilege, and thus do not work on OpenShift out of the box. This can be worked around by allowing OpenShift to allow root containers (see https://serverfault.com/a/920539):

oc adm policy add-scc-to-user anyuid -z default

We should investigate what options we have here for getting our charts working on OpenShift. At the very least, we should document this issue for OpenShift users.
