Use labels to identify ResourceClaim/Handle/Pool on created resources

[jkupferer]

There are currently annotations on created resources, but not labels. The values that are annotations that should likely be labels are:

      poolboy.gpte.redhat.com/resource-claim-name: ...
      poolboy.gpte.redhat.com/resource-claim-namespace: ...
      poolboy.gpte.redhat.com/resource-handle-name: ...
      poolboy.gpte.redhat.com/resource-handle-namespace: ...
      poolboy.gpte.redhat.com/resource-provider-name: ...
      poolboy.gpte.redhat.com/resource-provider-namespace: ...

We would need to continue to set both labels and annotations for several releases when the labels are added.
