kubeadm: update section about CA certs in high-availability.md (#8917)

Browse Source 
Added information to install cfssl and cfssljson on all etc nodes as they are required to generate clients certificates
Change <podname> to <name> in static pod yaml description for etcd deployment

Additionaly the first bash script in "Run kubeadm init on master0" section doesn't render correctly on kubernetes.io site (https://kubernetes.io/docs/setup/independent/high-availability/) but I don't see any pb with markdown.
