Warnings related to deprecated ingress api version / Kubernetes 1.22+ support

[rombert]

Hi,

I have deployed IMC on a kubernetes cluster that is running on version 1.21 . I plan to move to 1.22 soon. I have noticed these warnings in the logs

W1223 10:03:50.082652       1 warnings.go:70] extensions/v1beta1 Ingress is deprecated in v1.14+, unavailable in v1.22+; use networking.k8s.io/v1 Ingress

This makes the think that the controller will not work with Kubernetes 1.22 or newer. It would be great it it could be updated for these newer Kubernetes versions.

FWIW, this is not working at all in 1.22

It would be great is someone could contribute a fix, I'd be happy to test it out.
