// CreateActivityRequest returns a request value for making API operation for
// AWS Step Functions.
//
// Creates an activity. An activity is a task that you write in any programming
// language and host on any machine that has access to AWS Step Functions. Activities
// must poll Step Functions using the GetActivityTask API action and respond
// using SendTask* API actions. This function lets Step Functions know the existence
// of your activity and returns an identifier for use in a state machine and
// when polling from the activity.
//
// This operation is eventually consistent. The results are best effort and
// may not reflect very recent updates and changes.
//
// CreateActivity is an idempotent API. Subsequent requests won’t create a
// duplicate resource if it was already created. CreateActivity's idempotency
// check is based on the activity name. If a following request has different
// tags values, Step Functions will ignore these differences and treat it as
// an idempotent request of the previous. In this case, tags will not be updated,
// even if they are different.
//
//    // Example sending a request using CreateActivityRequest.
//    req := client.CreateActivityRequest(params)
//    resp, err := req.Send(context.TODO())
//    if err == nil {
//        fmt.Println(resp)
