Currently it isn't possible to set extra labels on pods that use the labels snippet. This means users are required to fork the helm repository for OpenStack services to add custom labels. Use cases for this are for example injecting Istio sidecars. This change introduces the ability to set one set of labels on all resources that use the labels snippet.
