Deprecated apiVersion used for MutatingWebhookConfiguration and CertificateSigningRequest

[nluckenbill]

Hello, when creating a new admission controller, eksctl prints out the following warnings:

warnings.go:67] certificates.k8s.io/v1beta1 CertificateSigningRequest is deprecated in v1.19+, unavailable in v1.22+; use certificates.k8s.io/v1 CertificateSigningRequest

warnings.go:67] admissionregistration.k8s.io/v1beta1 MutatingWebhookConfiguration is deprecated in v1.16+, unavailable in v1.22+; use admissionregistration.k8s.io/v1 MutatingWebhookConfiguration

This can be reproduced following the instructions here:

Thanks for the heads-up, we'll work on this soon.

@cPu1 are you actively writing this at the moment? If not can you un-assign and throw it back into the pool?

In addition to switching to the stable API versions, it will be best to stay away from the Legacy K8s signer, and instead use cert-manager or similar tool to issue the certificate for the admission webhook.

@cPu1 do you know if we are still blocked upstream on this?
