Tolerate the control-plane taint

[jsturtevant]

After kubernetes/kubernetes#107533 and kubernetes-sigs/cluster-api-provider-azure#2098 Clusters my have the taint node-role.kubernetes.io/control-plane. This is toleration is needed for the k/k e2e suite where GMSA and this script are used https://github.com/kubernetes/kubernetes/blob/8c1dc25745480b280b38933ed3532e0830f58056/test/e2e/windows/gmsa_full.go#L270
