* Add osprofiler wsgi middleware. This middleware is used for 2 things:
1) It checks that person who wants to trace is trusted and knows
secret HMAC key.
2) It starts tracing in case of proper trace headers
and adds first wsgi trace point, with info about HTTP request
* Add initialization of osprofiler at start of service
Currently that includes oslo.messaging notifer instance creation
to send Ceilometer backend notifications.
* Traces HTTP/RPC/DB API calls
