Add support for DM

[dveeden]

Closes: #97

I added the two template config files with the logging commented out and copied one of the compose files and added this:

  dm-master:
    image: pingcap/dm:latest
    volumes:
      - ./config/dm-master.toml:/dm-master.toml:ro
      - ./logs:/logs
    command:
      - /dm-master
      - --log-file=/logs/dm-master.log
      - --config=/dm-master.toml
    restart: on-failure
  dm-worker0:
    image: pingcap/dm:latest
    volumes:
      - ./config/dm-worker.toml:/dm-worker.toml:ro
      - ./logs:/logs
    command:
      - /dm-worker
      - --log-file=/logs/dm-worker0.log
      - --config=/dm-worker.toml
    restart: on-failure

Not sure what else is needed to get this to properly support DM
