feat: add customized tekton pipeline to build image from tag

- image should store in quay.io/opendatahub and tagged with the same git
  tag: vx.y.z matching upstream llm-d-router release
- to retrigger build in case build failure, force push tag, on-command
  wont work in this case without specify tag name
