[ingress-nginx] missing resources (ingressClass, services, maybe more)

[peschmae]

After deploying a new cluster with kubespray and ingress-nginx enabled, there is no IngressClass resource created.
The IngressClass resource was introduced in 1.18, and the annotation kubernetes.io/ingress.class is deprecated these days.
It seems a while back the ingress-nginx version in kubespray was updated, but the new resources introduced weren't copied over.

Additionally there are also multiple services that would normally be created if one uses the official deployment files: e.g.
https://raw.githubusercontent.com/kubernetes/ingress-nginx/main/deploy/static/provider/baremetal/deploy.yaml or https://raw.githubusercontent.com/kubernetes/ingress-nginx/main/deploy/static/provider/cloud/deploy.yaml

I think adding at least the IngressClass would be useful, adding the services will be more work and require some changes to the deployment which will make it harder to ensure not to brake existing clusters.

Maybe instead of introducing the services, it would be an option to provide a way to deploy ingress-nginx through the helm-apps role, and just add the IngressClass to the existing role to move away from the deprecated annotation.

Environment:

• Cloud provider or hardware configuration:
  Proxmox / Baremetal
• OS (printf "$(uname -srm)\n$(cat /etc/os-release)\n"):
  Ansible node: Linux 5.10.0-21-amd64 x86_64 / PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"
  Kubernetes Master & Workers: Linux 6.1.0-6-amd64 x86_64 PRETTY_NAME="Debian GNU/Linux 12 (bookworm)"

Kubespray version (commit) (git rev-parse --short HEAD): 3450865

Network plugin used: Cilium

Command used to invoke ansible:
ansible-playbook -i inventory/mycluster/hosts.yml cluster.yml -b -v

Output of ansible run:
Success

Hi @kundan2707
Are you intending to work on this for #10075 ?
Otherwise I'll make a pull reuqest adding the ingressClass resource, to solve #10014 and make the nginx ignress more future proof
