WIP: make openshift-deploy a sibling to openshift-router
Reorganize the OpenShift builds into three stages

* Base image - based on CentOS 7 and are the core for other images
* Release image - a Git cross-platform compile environment that isolates external dependencies
* Origin and other dependent images

The release build generates a set of tar archives containing the binaries for each platform.
The origin image uses the binary from the release, without the Git environment. The remaining
platform images are based on the origin image and do no builds of their own.
WIP - Share vars
Rename kube-deploy -> origin-deployer and gofmt
