Implement support for kubeadm v1beta4 API

[fabriziopandini]

What would you like to be added (User Story)?

As a user, I want to be able to create clusters with kubeadm 1.31 (which most probably is going to use v1beta4 API)
As a user, I want to be able to use latest and greatest introduced by kubeadm v1beta4 API

rif kubernetes/kubernetes#125029

Action Plan

Mandatory tasks to support Kubernetes v1.31:

• Implements conversions from CAPI v1beta1 types to kubeadm v1beta4 ✨ Add kubeadm v1beta4 types #10709
  • Special handling should be implemented for ClusterConfiguration.TimeoutForControlPlane and JoinConfiguration.Discovery.Timeout

Optional non breaking changes to be implemented ASAP:

•  Before adding new fields, check potential impacts on things like

  cluster-api/controlplane/kubeadm/internal/filters.go

  Line 220 in 57dc231

  match, diff, err := compare.Diff(machineClusterConfig, kcpLocalClusterConfiguration)

  , also ClusterClass and topology reconcile ✨ Add ExtraEnvs and ImagePullSerial to KubeadmConfig #10846
• Add ClusterConfiguration.*.ExtraEnvs ✨ Add ExtraEnvs and ImagePullSerial to KubeadmConfig #10846
• Add Init/JoinConfiguration.NodeRegistrationOptions.ImagePullSerial ✨ Add ExtraEnvs and ImagePullSerial to KubeadmConfig #10846
• Add Init/JoinConfiguration.Timeout: ⚠️ Align KubeadmConfig to kubeadm v1beta4 types #12282
  • Important: Timeout.ControlPlaneComponentHealthCheck and Timeout.TLSBootstrap must not be added now to ensure a clean migration of ClusterConfiguration.TimeoutForControlPlane and JoinConfiguration.Discovery.Timeout when we introduce CAPI v1beta2 types

Changes deferred to when we implemening CAPI v1beta2 types

• Refactor ClusterConfiguration.*.ExtraArgs and Init/JoinConfiguration.NodeRegistrationOptions.KubeletExtraArgs ⚠️ Align KubeadmConfig to kubeadm v1beta4 types #12282
• Add Timeout.ControlPlaneComponentHealthCheck and Timeout.TLSBootstrap and remove ClusterConfiguration.TimeoutForControlPlane and JoinConfiguration.Discovery.Timeout ⚠️ Align KubeadmConfig to kubeadm v1beta4 types #12282
• change type for ImagePullPolicy ⚠️ Align KubeadmConfig to kubeadm v1beta4 types #12282

Changes deferred to when we review certificate management / renewal --> #12289

Changes deferred to when we review kubeadm/KCP addon management --> #12288

Changes deferred to when we implement EncryptionAlgorithm for certificates -> #10077

note: priority assumes we can continue to work with v1beta3 API, but if this is not true it must be bumped to critical-urgent
