Deregistering a scalable target deletes the scaling policies that are associated with it.
To create a scalable target or update an existing one, see RegisterScalableTarget.
/// Concurrent updates caused an exception, for example, if you request an update to an
/// Application Auto Scaling resource that already has a pending update.
///
/// The service encountered an internal error.
///
/// The specified object could not be found. For any Put or Register
/// API operation, which depends on the existence of a scalable target, this exception
/// is thrown if the scalable target with the specified service namespace, resource ID,
/// and scalable dimension does not exist. For any Delete or Deregister
/// API operation, this exception is thrown if the resource that is to be deleted or deregistered
/// cannot be found.
///
/// An exception was thrown for a validation issue. Review the available parameters for
/// the API request.
