Feature/trace propagation (#96)

Browse Source 
* add b3 header for trace propagation on initial webhook

* logging

* add tracing context to all webhooks

* Add span parameter to Task.getTracingPropagation. Pass proper span to getTracingPropagation calls in Task methods to propagate the proper spanId (#91)

* some tracing cleanup

* bugfix: azure stt results need to be ordered by confidence level before processing (#92)

* fix assertion

* bugfix: vad was not enabled on config verb, restart STT on empty transcript in gather

* gather: dont send webhook if call is gone

* rest outdial: handle 302 redirect so we can later cancel request if needed (#95)
