Erik Olof Gunnar Andersson 01eff94b76 Centralized configuration
Based upon the established conf paradigm used in Nova,
this patch moves the configuration to a central location.
Making config a lot easier to manage, as well a lot easier
to locate.

Additional changes
* Fixed missing notification section in example config.
* Moved external configs to generator config (e.g. osprofiler)
