The OSprofiler is a distributed trace toolkit library. It helps to trace internal calls of Openstack services including RPC, DB and WSGI. This patch integrates OSprofiler in Rally. Rally can trigger the profiling on a per-iteration basis. To do so a secret key (profiler_hmac_key) is stored alongside the credentials and used to initialize the profiler in the constructor of the scenarios. A configuration parameter (enable_profiler) can disabled the profiling. Note that in this patch we don't embed the full osprofiler report but only a trace id. This trace id can be used to retrieve the full trace from the osprofiler tool later.
