Moritz Halbritter 61d7f3783e Implement config data loader to load from environment variables
The config data loader supports the env: prefix and also accepts
extension hints.

Example: env:VAR1[.properties] reads the environment
variable 'VAR1' in properties format (using the
PropertiesPropertySourceLoader).

The PropertySourceLoaders are loaded via spring.factories.

Also adds a smoke test to test it end to end.
