Add mappings for Webhook authorization mode.

[anderseknert]

Adding the missing parameters I reported as an issue the other day. First PR in a go repository so bear with me. Had a look at previous similar addition an tried to figure it out from there. Added a few tests to verify and tested setting up a new cluster with the added parameters as well.

Hi @anderseknert. 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.

Thanks for the contribution @anderseknert !

This looks great and love the unit tests!

That's an unusual syntax - I would have expected you could just use []*string{ v.AuthorizationMode, v.AuthorizationWebhookConfigFile}

[anderseknert]

I literally wrote my first lines of Go last week, so any unusual syntax is more due to incompetence rather than any desire to be different ;) In this case though I think I saw this syntax used on line 257 above and figured there's probably a point in doing it like that.

Thanks @anderseknert
