Katello-nightly-rpm-pipeline 514 failed

Katello nightly pipeline failed:

Repoclosure is failing again on webpack hash. We need a better way to handle this, failing builds every time something in core changes is leading to way too many broken nightlies.

I wonder if we should teach Foreman to check if the vendor hash changed and trigger a katello nightly build. On the other hand, that only fixes it for a single plugin. Luckily we only have a few plugins that use webpack.
