Subject: [PATCH] :whale: Add telegraf container for Docker metrics in influxdb

All our hosts running docker can put their metrics into our influxdb
now.

Note: not all docker hosts do this (yet), because the influxdb is
currently only reachable from within the local space internal network in
our rooms.
