To add new drivers you should, create new subclass of this class and
implement notify method.
:param info: Contains information about trace element.
In payload dict there are always 3 ids:
"base_id" - uuid that is common for all notifications
related to one trace. Used to simplify
retrieving of all trace elements from
Ceilometer.
"parent_id" - uuid of parent element in trace
"trace_id" - uuid of current element in trace
With parent_id and trace_id it's quite simple to build
tree of trace elements, which simplify analyze of trace.
:param context: request context that is mostly used to specify
current active user and tenant.
