ProjectClaim controller creates ProjectReference (#15)
Create ProjectReference from ProjectClaim When a ProjectClaim resource is created, a ProjectReference resource is automatically created in the operator namespace gcp-project-operator * ProjectClaimCRLink links to the corresponding ProjectClaim * ProjectReferenceCRLink links to the corresponding ProjectReference * LegalEntity content copied from ProjectClaim * When the ProjectClaim gets removed, the ProjectReference resource is removed automatically as well
