Epic: Add openshift support

[FabianKramm]

Use Case

Currently we already support multiple virtual distros in vcluster, but it would be nice for our enterprise customers that rely on openshift to add support for a virtual openshift distribution. It might be also very interesting to run a virtual openshift inside a regular kubernetes cluster.

Implementation

We need investigation around what controllers we need to support and if we would need to add extra syncers for those. These could be added in form of a plugin to vcluster itself.

++1 . isn't about just specifying 3 images: controllers , etcd and apiserver ? if so, can't we use same Openshift release image?

@abdennour You can probably use OpenShift images for those. But OpenShift comes with more APIs and controllers (DeploymentConfig, Project, Route, etc.) that are treated as integral part of "an openshift cluster", and those require additional components and work from vcluster maintainers to adopt them.
