Front demo project

pre-condition:

1. Tekton pipeline, triggers installed
2. Istio installed
3. Iter8 installed
4. Namespace with Istio proxy auto injection enabled created (init.yaml)
5. One version of the project installed.
6. Service for the project created (init.yaml)
7. The front application that sends the requst to the demo porject installed (https://github.com/akihikokuroda/iter8-front)
8. Tekton resources for this demo (task, pipeline, eventlistener, triggerbindings, triggertemplates) installed
9. Hooks in the demo github repository created.

Step:

Manual step:

1. update the app to respond slowly
2. create a pull request

Event listener execute a pipeline:

1. pipeline - build/ push app (existing task -pipeline hotel)
2. pipeline - deploy app (existing task - pipeline hotel)
3. pipeline - create iter8 experiment (new catalog task)
4. wait for experiment completion (new catalog task)

Experiment fails:

1. delete the new deployment (new catalog/sample task)
2. add comment and change the pull request status (existing catalog task)
3. send a slack message (existing catalog task)
4. send an email

Manual:

1. update the app to respond faster
2. push the update

Event listener execute a pipeline:

(same as above)

Experiment success:

1. change the pull request status (existing catalog task)
2. delete the original deployment (new catalog/sample task)
3. send a slack message (existing catalog task)
4. send an email
