// Create an App Runner automatic scaling configuration resource. App Runner
// requires this resource when you create or update App Runner services and you
// require non-default auto scaling settings. You can share an auto scaling
// configuration across multiple services. Create multiple revisions of a
// configuration by calling this action multiple times using the same
// AutoScalingConfigurationName . The call returns incremental
// AutoScalingConfigurationRevision values. When you create a service and configure
// an auto scaling configuration resource, the service uses the latest active
// revision of the auto scaling configuration by default. You can optionally
// configure the service to use a specific revision. Configure a higher MinSize to
// increase the spread of your App Runner service over more Availability Zones in
// the Amazon Web Services Region. The tradeoff is a higher minimal cost. Configure
// a lower MaxSize to control your cost. The tradeoff is lower responsiveness
// during peak demand.

	// DefaultConfiguration that App Runner provides:
	//   - Create new revisions of the DefaultConfiguration .
	//   - Delete the revisions of the DefaultConfiguration .
	//   - Delete the auto scaling configuration for which the App Runner
	//   DefaultConfiguration was created.

	//   auto scaling configuration with the same DefaultConfiguration name. The
