Let the K8S cluster decide on ipFamily usage

[macwinnie]

Hi Team =)

We also ran into the No-Startup issue in our IPv6 only K8s cluster, I read about in #1380 – and the solution is as simple as letting the cluster decide on ipFamily usage.
I did not find any reason why the Pulp operator should keep requiring ipFamilyPolicy: SingleStack or should be locked in with IPv4 family – and would be happy to contribute these changes into the project =)

All the best,
Martin

Hi @macwinnie. Thanks for your PR.

I'm waiting for a pulp 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.
