VOL-1460: Docker builds now use common base image. Also Documentation Update.
Modified all docker files to use a base build that copies in vendor and
other common GOPATH items. Then each dependant Dockerfile
uses the base and only copies in golang source needed to build.
Also grab updated lock file and vendor items missing (from a dep ensure)
for build to work.
