Generate CRD with Controller Gen v0.3.0

[dvaldivia]

Reverting the CRD to controller-gen@v0.3.0 because the never CRD generated with v0.4.0 was failing on a k8s cluster.

The failure was that the annotations for the Tenant.Spec.Zone[].VolumeClaimTemplate the metadata of the volume template was not being stored at the k8s api server level, by reverting to a CRD generated with v0.3.0 the problem was fixed, we need to investigate further to determine what is v0.4.0 controller-gen doing wrong .

Some of the error that were thrown with the CRD that is being replaced:
