Publish a new set of demos on YouTube

Use the new flow that we used at k8s meetup for twitter-stats example:

1. Point to clusters
2. Import service 1
3. Import service 2
4. Import rules
5. Deploy two dev envs with mock data
6. Deploy prod env with real-time data
7. Show update of prod env with real twitter tokens
8. Integration with CD

We also need an updated video on the service model: https://www.youtube.com/watch?v=wHEcpkPCkpk
