fix typo / error regarding etcd and k8s_cluster groups (#8580)
As far as I can tell this is simply a typo that has existed from the beginning. Having it this way around (`etcd` group as a child and thus subset of `k8s_cluster`) mirrors what is written in the preceeding sentence.

Update node about container_manager variable (#7911)
I was deploy my cluster with separate etcd cluster and not intersect with kube_control_plane or kube_node. And I want to run etcd cluster in docker but still used containerd to make container runtime for all other nodes. Therefore, I was added note to this doc for everyone 

Thank !
