Osprofiler notification plugin

Registered by Boris Pavlovic

Intro
=====

In OpenStack we have bunch of services inside every project. It's really hard
to understand where and why your request works slow. To resolve this issue we
introduce tiny library, that can be easily integrated in all existing service
and will allow us to get 1 trace (tree of elements) per API request.
It's simpler to see, then to explain sample:

To resolve this task, we have to send from all services to some common
collector special notifications. As there is already Ceilometer, that is
integrated with everything and as well notification API that perfectly works
for us we decide to use it (Ceilometer).
