Refactor docker-compose services - these really belong in
lib/orchestration/services/<service-name>/docker_compose.rb

Add default logging section to each service ?

Redis support

Use `Paint` instead of `Colorize` for colouring output - better licensing and no
monkeypatching `String` etc.

Make unicorn `config.rb` resilient to database connectivity failures

Group healthcheck rake tasks - run all at once in the same process. Create a
master process that generates config files and calls each healthcheck in batch.

Provide a way of declaratively configuring bespoke healthchecks.

Auto-healthcheck any services with a local port bind using the Listener
healthcheck.

Add remote Docker swarm management.
