workspaces VW: remove the need of a SAR against CWT

[davidfestal]

We should completely remove the need of issuing a SAR against ClusterWorkspaceType in the Create implementation of the workspaces virtual workspace.

This SAR simply forces the VW to set a static default CWT reference, which should be done by the admission controller.

But removing this SAR requires updating the CWT admission controllers to take in account the owner annotation set by the VW, when it is there (and user is the system:apiserver).
