WIP: Generate Map of Config Profiles from Spring Environment

Augmenter
- Replace default Config Profile with map of Config Profiles. Now,
  Augmenter can choose a config profile at runtime and augment it.
- Move Augmenter to sub package.

WIP
- Implement ConfigProfileGenerator, which retrieves Config profiles
  from Spring Environment and returns an easy-to-use map with
  profiles that is keyed with profile id's.
- Replace application.properties with application.yaml.
- Remove Augmenter test cases: They need to be adapted.
