Description

This makes testing configuration components easier.

For exemple  subclassing  PropertiesProvider to make it return an in memory configuration such as a MapConfiguration instead of being bound to the concrete PropertiesConfiguration implementation.

I have found no place in the project where relying on the concrete type is actually useful. All uses were replaceable by the interface or by a static call to the top of the hierarchy (AbstractConfiguration).
