CoreDNS Update Addon Wait

[reganmcdonalds4]

What were you trying to accomplish?

Update EKS addon coredns with eksctl.

What happened?

When updating coredns with the --wait argument, the command exits immediately after beginning the update. We are left unaware if the update was successful or not. In our case, the update failed silently from the perspective of eksctl.

How to reproduce it?

Set minAvailable: 1 for the coredns pod disruption budget and run:

 eksctl update addon --cluster cluster-name \
  --name coredns \
  --version latest \
  --wait \
  --force

Can you rerun the command with debug logging enabled, by passing -v4?

Here is the output when passing -v4. The command exits while the update is still in progress:

@reganmcdonalds4 I think that's sufficient. We are occupied with other priorities right now, so please give us some time.
