Implement group resource (#181)

This change implements a new group resource. 

It also sets the standard for a resource reference will be done through
out the controller. A resource reference can either be done by ID or as
a local named reference to the actual resource. This allows end users to
chose if they want to manage things completely in the cluster or not.
