[metrics-server addon] Restore connecting to nodes via IP addresses

[serathius]

This preference list matches is used to pick prefered field from k8s
node object. It was introduced in metrics-server 0.3 and changed default
behaviour to use DNS instead of IP addresses. It was merged into k8s
1.12 and caused breaking change by introducing dependency on DNS
configuration.

[metrics-server addon] Restore connecting to nodes via IP addresses

[k8s-ci-robot]

Hi @serathius. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
