This command will generate labels for each service which correspond to the
following format:

    coop-cloud.${STACK_NAME}.${SERVICE_NAME}.version=${IMAGE_TAG}-${IMAGE_DIGEST}

The <recipe> configuration will be updated on the local file system. These
labels are consumed by abra in other command invocations and used to determine
the versioning metadata of up-and-running containers are.
