// Creates a key group that you can use with CloudFront signed URLs and signed
// cookies (https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/PrivateContent.html)
// . To create a key group, you must specify at least one public key for the key
// group. After you create a key group, you can reference it from one or more cache
// behaviors. When you reference a key group in a cache behavior, CloudFront
// requires signed URLs or signed cookies for all requests that match the cache
// behavior. The URLs or cookies must be signed with a private key whose
// corresponding public key is in the key group. The signed URL or cookie contains
// information about which public key CloudFront should use to verify the
// signature. For more information, see Serving private content (https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/PrivateContent.html)
// in the Amazon CloudFront Developer Guide.
