kubernetes v1.22: Update controller to use networking.k8s.io/v1 Ingress.

[andrewstuart]

Description

This PR should fix the problem of external-dns not running in v1.22. It does not provide backwards compatibility for extensions/v1beta1 ingresses as this should still be backwards compatible going back to v1.19 without any other code; I don't know the typical policy for this SIG, but given that v1beta1 Ingress has been removed, this seems safe enough (and much simpler).

Fixes #2168

Checklist

• Unit tests updated
• End user documentation updated

@andrewstuart I think this is a fair change and as breaking as it could be, it's has been plenty of kubernetes releases already that those APIVersions are available.

Could anyone give me some help about when this issue is expected to be released? Currently I could see that it's in master branch, but I don't know if this issue will be include in next release (I suppose yes) and when next release will be ready to be used.

Thank you so much!
