Initial KPI/PM support
Added a tiny program (and container) to shovel KPI
data from Kafka to graphite using carbon pickle
format. The utility is called 'shovel'. It is dockerized.
Reorganized Dockerfiles in their own dir to start cleaning
up top-level dir of Voltha.
A 3rd-party grafana/graphite container is added to the
system test ensamble, launched by docker-compose. With
the new shovel, this implements a KPI/PM metric store
with a very nice Web UI (grafana).
Finalized internal sample format and extended the new
diagnostics module to publish 2 initial metrics to
Kafka, which now nicely shows up via both kafkacat
and grafana.
The infrastructure is ready for arbitrary metrics now.
This commit accidentally picked up some ongoing change
on the Tibit integation side, but it is too complex
to untangle, so I leave it in; Nathan will push his
latest Tibit adapter code in the next 24h.
