Fix kubernetes-sigs#2640: Optionaly add CRD manifest for DNSEndpoint to helm deliverables
Since DNSEndpoint can be used as one of the sources for external-dns, it would be handy to be able to deploy its definition file together with the main deployment. More info: - piggy-backing on the make crd to create such template file under charts/external-dns/templates/ - by default it's the same as before and the CRD is not deployed using helm chart - to enable the CRD deployment, one has to set helm value deployCrd=true Signed-off-by: Jirka Kremser <[email protected]>
