Deletes the specified session entity type.

Example:
    >>> import dialogflow_v2
    >>>
    >>> client = dialogflow_v2.SessionEntityTypesClient()
    >>>
    >>> name = client.session_entity_type_path('[PROJECT]', '[SESSION]', '[ENTITY_TYPE]')
    >>>
    >>> client.delete_session_entity_type(name)

Args:
    name (str): Required. The name of the entity type to delete. Format:
        ``projects/<Project ID>/agent/sessions/<Session ID>/entityTypes/<Entity Type
        Display Name>``.
    retry (Optional[google.api_core.retry.Retry]):  A retry object used
        to retry requests. If ``None`` is specified, requests will not
        be retried.
    timeout (Optional[float]): The amount of time, in seconds, to wait
        for the request to complete. Note that if ``retry`` is
        specified, the timeout applies to each individual attempt.
    metadata (Optional[Sequence[Tuple[str, str]]]): Additional metadata
        that is provided to the method.

Raises:
    google.api_core.exceptions.GoogleAPICallError: If the request
            failed for any reason.
    google.api_core.exceptions.RetryError: If the request failed due
            to a retryable error and retry attempts failed.
    ValueError: If the parameters are invalid.
