Two bug fixes to HA guide for kubeadm: (#7451) 

- In the provided configuration file for `kubeadm init` the value for
`apiserver-count` needs to be put in quotes.
- In addition to /etc/kubernetes/pki/ca.* also /etc/kubernetes/pki/sa.*
need to be copied to the additional masters. See [this

@petergardfjall for details.
