Add handler for Sentry

Registered by Jan Vondra

It would be nice to allow using sentry for openstack services (https://sentry.io/welcome/). Basically it would mean only adding the raven handler and setting up a DSN during init of the helper.
relevant sentry documentation: https://docs.sentry.io/clients/python/integrations/logging/
