class_docstr: Polls asynchronously for the existence of a blob in a WASB container.
  
  This class is deprecated and will be removed in a future release.
  
  Please use :class:`airflow.providers.microsoft.azure.sensors.wasb.WasbBlobSensor`
  and set *deferrable* attribute to *True* instead.
  
  :param container_name: name of the container in which the blob should be searched for
  :param blob_name: name of the blob to check existence for
  :param wasb_conn_id: the connection identifier for connecting to Azure WASB
  :param poke_interval:  polling period in seconds to check for the status
  :param public_read: whether an anonymous public read access should be used. Default is False
  :param timeout: Time, in seconds before the task times out and fails.
