// Creates a launch of a given feature. Before you create a launch, you must
// create the feature to use for the launch. You can use a launch to safely
// validate new features by serving them to a specified percentage of your users
// while you roll out the feature. You can monitor the performance of the new
// feature to help you decide when to ramp up traffic to more users. This helps you
// reduce risk and identify unintended consequences before you fully launch the
// feature. Don't use this operation to update an existing launch. Instead, use
