Fixed `tls-server-name` (SNI)  property usage when explicitly set in kubeconfig.

Unfortunately I think this file is generated, in order to make permanent changes here I believe the PR would need to go to the generator repo

Can you provide some more information on what to do? Because the gen repo doesn't really say nor point to what needs to be updated. The contributing guide doesn't go into detail either.

This file seems to ref https://github.com/kubernetes-client/gen/blob/master/proto/dependencies.sh even more generated files from the apimachinery repo.

@fabianvf @yliaog

The auto-generated code is available for openapi-generator version >=6.6.0 (PR).

Since this repo uses version v4.3.0, I decided to apply a patch - similar to the current one that exists - to apply the necessary changes to support SNI. Once we start using a version that includes the upstream fix, the patch can be safely removed.

Can you please check it again?
