Boris Pavlovic ac3949427a Added osprofiler notifications plugin
As a default osprofiler notification driver in OpenStack
we are going to use notifier based on oslo.messaging.

These messages will send notification with event_type
"profiler.*" so we will be able to manage them separately
from other messages in "notifications.*"

Actually 1 osprofiler trace has a lot of notifications, so to be able
to retrieve them via ceilometer API in one request, we are using specific
specific resource_id, "profiler-<base_id>". We are using base_id in resource_id
case base_id is common id for all notifications related to one trace.

Implements bp osprofiler-plugin
