Cause

This issue is related to the following Github issues:https://github.com/spinnaker/spinnaker/issues/5040https://github.com/spinnaker/clouddriver/pull/5248 As reported, Kubernetes has a bug where it will not see the manifest properly and will therefore error out. When utilizing the Deploy (Manifest) stage with Red/Black rollout strategy, a requirement of using this stage was for a Service to exist before running the stage in order to read its selector and apply it to the newly deployed replicaset.  This requirement has been updated, so that now the Service will first be read from the stage manifest list, and if not found it will proceed with the same behaviour as before, reading it live from the cluster.
