Comment 1 for bug 1282150

by submitting the release jobs with higher priority, it can make the release jobs run before daily build jobs,
but still have a problem, hope we can consider it together this time.

wrongly submitted release jobs need to be cancelled manually.
like today, we trigger the release#1 build, but we found it use the wrong manifest after the jobs submitted to LAVA.
after we created the release#3 build, its jobs are queued after the jobs of release#1 build since they will have the same HIGH priority.
