Docker Compose Support

[newcron]

It would be great if athena would provide first–class docker-compose support to allow for a better startup of more complex environment (e.g. in an integration test, when mySQL and ElasticSearch is necessary), docker compose is really helpful for that.

Additionally, it would be great to specify a list of await commands that are executed until the exit with code 0 (e.g. a curl request that checks if elastic search has booted yet).
