Update 08-bootstrapping-kubernetes-controllers.md

[jerem0808]

encryption-config.yaml cannot be copied over /var/lib/kubernetes because it was moved during the step 6. So it doesn't exist anymore in the home folder.

vagrant@master-1:~$ {                                               
>   sudo mkdir -p /var/lib/kubernetes/                              
>                                                                   
>   sudo cp ca.crt ca.key kube-apiserver.crt kube-apiserver.key \   
>     service-account.key service-account.crt \                     
>     etcd-server.key etcd-server.crt \                             
>     encryption-config.yaml /var/lib/kubernetes/                   
> }                                                                 
cp: cannot stat 'encryption-config.yaml': No such file or directory
