When a DBaaSConnection CR is updated without spec changes, for instance, adding a label to the CR, the update would fail with a webhook error like below:

oc edit dbaasconnection myconnection2

error: dbaasconnections.dbaas.redhat.com "myconnection2" could not be patched: Internal error occurred: failed calling webhook "vdbaasconnection.kb.io": failed to call webhook: Post "https://dbaas-operator-controller-manager-service.openshift-dbaas-operator.svc:443/validate-dbaas-redhat-com-v1alpha1-dbaasconnection?timeout=10s": EOF
