@sardell To get this running in full dev, I had to change a line in the
metron.spec file for the RPMs to build properly.
`%attr(0644,root,root) %{metron_home}/web/alerts-ui/*.bundle.css` to
`/usr/metron/0.5.1/web/alerts-ui/styles.*.css`. I assume this is a just a
naming change, but I wanted to confirm that with you.---
