Add control-plane toleration to Agent K8S manifests. (#864)

* Add toleration to elastic-agent Kubernetes manifests. The toleration with key node-role.kubernetes.io/control-plane is set to replace the deprecated toleration with key node-role.kubernetes.io/master which will be removed by Kubernetes v1.25 * Remove outdated "master" node terminology. (cherry picked from commit 689aee3)
