Description

Currently the docker containers include a bunch of config files copied indiscriminately from the dev environment. Mostly these aren't valid for a production container and it's expected that the real config files will be mounted at /opt/impala/conf.

We should instead include a more reasonable set of default configs (e.g. for admission control), plus placeholders for other config files that may need to be overridden with site-specific configs.
