Move configs out of dockerfiles into specific files

[jdenoc]

A few config files are generated at build and documented within dockerfiles. They should be separated into their own files stored in a directory (.docker/conf/).

Some examples:

• Move .docker/money-tracker.vhost.conf in a .docker/conf directory.
• app.dockerfile
