Merge pull request #1219 from deis/component-tests

test(components): add unit and functional tests, go integration tests
fix(services): prevent units from stopping as "failed/failed"

Deis' systemd units always return "failed/failed" after being stopped
by fleetctl. Somehow our ExecStop command to remove the service container
conflicts with our ExecStart command and causes it to return an error code.
This is fixed by removing the ExecStop commands and adding a `--rm` flag
to the docker command in ExecStart. Additionally, our on_exit() handler in
each /app/bin/boot script was not returning 0.

TESTING: Run `make run`, then `make stop` on a Deis cluster. You should see
all units stop and return to "inactive/dead" status, whereas before they
would show "failed/failed."
