Support Tekton as CI/CD tools

Tekton is a cloud-native CI/CD project.
Compared to Jenkins, Tekton can take full advantage of the Kubernetes ecosystem.
For example, Tekton is a serverless component that is very easy to expand.
However, since Tekton lacks a user-friendly user interface, it may be difficult for new users to operate it.

So how about integrate Tekton as a new implement for CI/CD excution server.

The issue names no files, tests, or entry points. Start by surveying the repository's CI/CD integration and Kubernetes-related areas, then compare their execution model with Tekton. Done means defining and implementing a complete Tekton execution-server integration with a clear user-facing operation path.
