During Berlin Summit 2018 it was decided to start implementation
of the project cleanup in the SDK. This is a foundation for that
with the required bits and few examples in the services to demonstrate
the interface.
In the followup changes following should be done:
- review cleanup in service proxies (the ones implemented and not)
- describe the feature in the documentation
- start consuming this service from the OSC (need help deciding where
should it be implemented - core OSC, separate project, OSC plugin in
SDK, ...)
