Add Fleet/systemd configs.
No use maintaining our own CloudFormation config if CoreOS provides and maintains a really nice one for us.
Work around limitations in systemd and docker to get environment variables from etcd passed on to the docker container.
Tweaks to Fleet configuration. Support for specifying Redis host and port via environment variables.
Conditional builds.
Add dump command. Add --format flag to dump and show commands.

The --format flag means dump and show can now output to JSON and YAML.
