Description

Newer OSGi specs usually always contain a DTO api which allows to get the current state of the implementation, e.g. the framework state, DS provides component states, the http whiteboard allows to inspect the registered servlets etc.
The nice thing of using such DTOs is that they are easily serializable (ootb, rules are defined) and should be well known to OSGi aware developers.
We should add such DTOs at least for the resource tree: mounted providers, their configurations etc.
