Talos generates in-cluster kubeconfig for the kube-scheduler and kube-controller-manager to authenticate to kube-apiserver. Bug was that validity of that kubeconfig was set to 24h by mistake. Fix that by bumping validity to default for other Kubernetes certs (1 year). Add a certificate refresh at 50% of the validity. Fix bugs with copying secret resources which was leading to updates not being propagated correctly. Signed-off-by: Andrey Smirnov <smirnov.andrey@gmail.com>
