   Export entities from Google Cloud Datastore to Cloud Storage

   :param bucket: name of the cloud storage bucket to backup data
   :type bucket: str
   :param namespace: optional namespace path in the specified Cloud Storage bucket
       to backup data. If this namespace does not exist in GCS, it will be created.
   :type namespace: str
   :param datastore_conn_id: the name of the Datastore connection id to use
   :type datastore_conn_id: str
   :param cloud_storage_conn_id: the name of the cloud storage connection id to
       force-write backup
   :type cloud_storage_conn_id: str
   :param delegate_to: The account to impersonate, if any.
       For this to work, the service account making the request must have domain-wide
       delegation enabled.
   :type delegate_to: str
   :param entity_filter: description of what data from the project is included in the
       export, refer to
       https://cloud.google.com/datastore/docs/reference/rest/Shared.Types/EntityFilter
   :type entity_filter: dict
   :param labels: client-assigned labels for cloud storage
   :type labels: dict
   :param polling_interval_in_seconds: number of seconds to wait before polling for
       execution status again
   :type polling_interval_in_seconds: int
   :param overwrite_existing: if the storage bucket + namespace is not empty, it will be
       emptied prior to exports. This enables overwriting existing backups.
   :type overwrite_existing: bool
   :param xcom_push: push operation name to xcom for reference
   :type xcom_push: bool
