Add support for retryable trait

[sugmanue]

Motivation and Context

Currently service models support adding a retryable trait (e.g. nimble or identitystore). This change adds support to honoring this trait by adding an override to a new method in the SdkServiceException class and another override to an existing method, e.g.,

/**
 * <p>
 * Indicates that the principal has crossed the throttling limits of the API operations.
 * </p>
 */
@Generated("software.amazon.awssdk:codegen")
public final class ThrottlingException extends IdentitystoreException implements
        ToCopyableBuilder<ThrottlingException.Builder, ThrottlingException> {

      ⋮
    @Override
    public boolean isRetryableException() {
        return true;
    }

    @Override
    public boolean isThrottlingException() {
        return true;
    }
      ⋮
}

nit: method name retryableOverrides() instead (to keep consistency with other calls to methodSpecs.addAll)?
