Code review comment for lp:~jcsackett/charmworld/trigger-test-builds

The jenkins_url/jenkins_token problem is not two points of change. The IP will change, the port may change. The job name can change. The token will change if we think it is compromised. Charmworld doesn't care about any of those details. We may not use Jenkins to test charms. We are certain of is that charmworld may need to tell some URI that a charm at a specific revision will be tested.
