Showcase Tekton pipeline

[lijcam]

Show some of the key differentiators of Tekton over other CI solutions. Chains? Container signing?

Concerns, problems, usecases

@shaneboulden I think you had some decent ideas around why Tekton.

I think for a start we should showcase a basic Tekton pipeline, like this example: https://github.com/shaneboulden/chat-pipeline

There's certainly a few advanced topics we could show beyond this:

• Tekton Chains and container signing
• Using pre-built ClusterTasks to make creating pipelines simpler (eg; the OpenShift client ClusterTask)
• Long-term storage of CI/CD jobs with Results
• Analysing DORA metrics with Pelorus (https://github.com/konveyor/pelorus)
• Integration with Azure DevOps
