Vendor and build without docker

This adds the vendor script from @cap10morgan and adds a "build docker without docker script". 

This attempts to share as much code as possible while introducing one script, hack/release/make-without-docker.sh, that sets up the GOPATH and builds. The vendor script and setup is also shared in the Dockefile.

No libraries are checked into the repo with this PR. Deps are fetched everytime vendor.sh is ran.
