WIP - docker registry as a pod inside openshift - card #338

This is initial part of the work contains following so far:
- [x] docker registry as a pod
- [x] pushing docker images into the registry after succesfull build
- [x] single run file that shows the whole process

Still todo:
- [ ] in depth documentation
- [ ] docker registry credentials
Like you said, we need to merge this w/ my example, i don't think we want to maintain two copies of this readme/scripts/etc.
