Avoid getting artifacts records directly from Jenkins

As you can see, we cannot use this function if the Jenkins server is down. But it still can work well if we put those data into the annotations of Pipeline.


Or, we could store those data in other places if it might let a CR be too big.

## Actions
- [ ] Deprecate the existing API
- [ ] Fetch data in the controller, and store it somewhere
