Deletes the specified Application Auto Scaling scaling policy.
Deleting a policy deletes the underlying alarm action, but does not delete the CloudWatch alarm associated with the scaling policy, even if it no longer has an associated action.
To create a scaling policy or update an existing one, see PutScalingPolicy.
/// 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
