✨ Pass the new GVK flag to azure manager

[Danil-Grigorev]

What this PR does / why we need it:

Since the introduction of the flags upstream in

• 🌱 Decouple MachinePool reconciler from Kubeadm kubernetes-sigs/cluster-api-provider-azure#4931
• ✨ Add aggregated role support kubernetes-sigs/cluster-api-provider-azure#4933

And implementing upstream kubernetes-sigs/cluster-api-provider-azure#4854, we need some changes to our turtles provider.

The CAPZ supports using different GVK for establishing controller to watch over changes within the bootstrap token. With that turtles will be able to leverage this flag for any user creating azure CAPIProvider.

The default value (set to watch RKE2Config for us) of the CLI flag can be overridden, if the CAPIProvider resource has additionally specified:

spec:
…
  deployment:
    containers:
    - args:
        --bootstrap-config-gvk: KubeadmConfig.v1beta1.bootstrap.cluster.x-k8s.io
      name: manager

This allows to run the CAPZ with kubeadm bootstrap/controlPlane provider if required.

Thanks for working on this @Danil-Grigorev. I'm looking at re-enabling E2E tests for Azure after this change.
