This commit adds the initial version of `create-cloud-deploy-release` as a Beta Gitlab Component,
    including CI tests, README and LICENSE.

    The `create-cloud-deploy-release` Gitlab Component creates a Google Cloud Cloud Deploy release, and automatcially promotes to the first tartget.
    The feature is simiar to [gcloud deploy release create](https://cloud.google.com/sdk/gcloud/reference/deploy/releases/create) gcloud command.

    The components relies on `identity: google_cloud` WIF to authenticate to Google Cloud services. At the commit point, `google_cloud_support_feature_flag` is required
    to use this Component.
