Docker images for Jenkins

This directory contains everything needed to build the Docker images that are used in our Jenkins setup. This is based off a similar setup in https://github.com/caffe2/caffe2/tree/master/docker/jenkins

The Dockerfiles located in subdirectories are parameterized to conditionally run build stages depending on build arguments passed to docker build. This lets us use only a few Dockerfiles for many images. The different configurations are identified by a freeform string that we call a build environment. This string is persisted in each image as the BUILD_ENVIRONMENT environment variable.

See build.sh for valid build environments (it's the giant switch).
