Package ClusterRunner using Docker container

Feature proposal for the following:
- **What:** Package ClusterRunner using Docker container
- **Why:** At my work, currently we strive to make **all** developer productivity tooling available to our developers via Docker container on CoreOS to prevent user space pollution, to delegate cross-platform portability to container engine, to avoid works-on-my-machine, etc. to name a few... :)
- **How:** I'd like to send a pull request that will package `mkdir -p ~/.clusterrunner/dist && cd ~/.clusterrunner && curl -L https://cloud.box.com/shared/static/2pl4pi6ykvrbb9d06t4m.tgz > clusterrunner.tgz && tar -zxvf clusterrunner.tgz -C ./dist && cp ./dist/conf/default_clusterrunner.conf clusterrunner.conf && chmod 600 clusterrunner.conf` using a minimal distro in a Docker container

Start with the issue's proposed download, extraction, configuration, and permissions command; no files or tests are named. Determine the minimal Docker packaging boundary for the ClusterRunner distribution and verify that the resulting image builds and supports the stated configuration setup.
