/// <remarks>
/// A template deployment that is currently running cannot be deleted. Deleting
/// a template deployment removes the associated deployment operations.
/// Deleting a template deployment does not affect the state of the resource
/// group. This is an asynchronous operation that returns a status of 202 until
/// the template deployment is successfully deleted. The Location response
/// header contains the URI that is used to obtain the status of the process.
/// While the process is running, a call to the URI in the Location header
/// returns a status of 202. When the process finishes, the URI in the Location
/// header returns a status of 204 on success. If the asynchronous request
/// failed, the URI in the Location header returns an error-level status code.
/// </remarks>
