Proposal: Kubernetes Build Plugin

We propose that a build plugin and corresponding framework be added to kubernetes to facilitate: 

1. Leveraging Kubernetes' scheduling, resource allocation, and garbage collection in order to provide docker image build capabilities to users
2. Third party systems wishing to use OTS Kubernetes as a build-farm
3. Organizations using a third-party CI server to orchestrate docker image builds as part of their devops SOPs
This is not a statement based on reality today, but at some point in the future you could have multiple masters working with the same registry (for scalability, redundancy, etc). If that's the case, you need to make sure you don't allow one to step over the other.
