Simon Pasquier a8fe172085 tests/e2e: add test to detect many-to-many errors
It happened quite a few times that some queries failed when Prometheus
scrapes metrics from 2 kube-state-metrics instances. This situation can
happen briefly when the kube-state-metrics instance is rolled out. It
might also be more apparent when automatic sharding of
kube-state-metrics is enabled.
