Kevin Carter 8d2e5f62a7 Implement shippable venvs
The change builds venvs in a single repo container and then
ships them to to all targets. The built venvs will be within
the repo servers and will allow for faster deployments,
upgrades, and more consistent deployments for the life cycle
of the deployment.

This will create a versioned tarball that will allow for
greater visablility into the build process as well as giving
deployers/developers the ability to compair a release in
place.
