Should this be

Suggested change

	- [ ] [Run release pipeline](https://ci.theforeman.org/job/candlepin-<%= release %>-rpm-pipeline/)
	- [ ] Kick off the [release pipeline](https://ci.theforeman.org/job/candlepin-<%= release %>-rpm-pipeline/) by calling <%= rel_eng_script('release_pipeline') %>

(requires a tiny adjustment in ci-jobs script to know how to call candlepin pipes)

We'll need to modify the procedure script:

$ ./procedure branch --project candlepin
./procedure:136:in `<main>': invalid argument: --project candlepin (OptionParser::InvalidArgument)

I ended up writing this patch

Please include my suggested changes to the procedure script.

I ended up creating ehelms#1 with my comments. If you merge theforeman/jenkins-jobs#484 and that PR I think my concerns are addressed.
