TestAccNetworkPolicies flake

[flostadler]

TestAccNetworkPolicies is flaky.

It's failing because one of the two coredns pods isn't ready: 6 out of 7 Pods are ready.
The coredns container of that pod seems to be restarting, I saw this in the logs: "restartCount": 4

I'm gonna dig a bit deeper if coredns needs some special configuration for network policies. It might be that we need to add some additional network policies for coredns to be allowed to properly communicate.

I'm starting to have a suspicion that we might be loading the account with too many clusters and nodes at once. Will do some digging if I can find out whether we're running into any limits (e.g. EC2 instance limits)
