// Creates a new User within a collection specified by CollectionId . Takes UserId
// as a parameter, which is a user provided ID which should be unique within the

// the UserId more user friendly. Uses a ClientToken , an idempotency token that
// ensures a call to CreateUser completes only once. If the value is not supplied,
// the AWS SDK generates an idempotency token for the requests. This prevents
// retries after a network error results from making multiple CreateUser calls.
