Proposal: Initial images proposal

This is a proposal to add a higher level image component that can keep track of Docker image repositories, images, and image metadata.
Not just in a PaaS - as an ops / dev team the actual push to production might be as simple as "tag this image as ready".  The hard part - QE and validation, happens up front.  The part afterwards (roll out to production) should be automated and leverage things like rolling deploys and canary testing automatically.

A very real problem in large organizations is ensuring that security updates are delivered in a timely mechanism to a large set of applications.  Most applications are not critical LOB (where downtimes are highly controlled) and are happy to have even one nine of reliability.  So organizationally having an automated chain from source -> production for things like security updates on top of images is an ideal default state, as long as the important no-downtime apps can be hand held.
