build infrastructure related random idea dump

[cgwalters]

1. Move to a jenkins instance in api.ci; see prow: Remove old branched openshift/os:latest build release#1000
   1a) Use GCE nested virt for vmimage builds
2. Split out the pipeline to a separate repo
3. Move to pinning all of the base (non-rdgo) RPMs in the manifest; updates to them are driven a bot that submits PRs. Think like what Cockpit does to update their VMs.
4. Change rdgo to work the same way but with git commits
   4a) Related, rewrite or replace/rework rpmdistro-gitoverlay
5. Containerize the imagefactory bits so we can consistently use containers and not classic systems
