app-base: 0004632: Move fast-updates repo to Koji/mirror system

Migrated from: https://tracker.clearos.com/view.php?id=4632

Reported by: PBaldwin

The clearos-bootstrap repo exists to get around limitations of the build and mirror systems. The repo will no longer be required once the following limitations have been removed:

• Ability to upload upstream tarballs (e.g. dropbox binaries) to the build system.

• Ability to update all mirrors on demand to deploy emergency fixes.

• Improved repo update time. Waiting half a day for a repo change is painful - the SDN/Marketplace repos are fully up-to-date every hour (and on demand).

• At least 2 developers (primary, backup) must be able to understand and fix build/mirror issues. In the past, we have had to wait on a single person for critical path issues. That's not sustainable.

Note: a speedy update repo was also discussed in the CentOS project. Details here: https://lists.centos.org/pipermail/centos-devel/2015-February/012718.html [^]
