what changed:
we had to refactor the bandwidth plugin and switch from a classless qdisc (tbf)
to a classful qdisc (htb).
subnets are to be provided in config or runtimeconfig just like other parameters
unit and integration tests were also adapted in consequence
unrelated changes:
test fixes: the most important tests were just silently skipped due to ginkgo Measure deprecation
(the ones actually checking the effectiveness of the traffic control)
