Remove line in /root/.ssh/authorized_keys for all machines

Tips: use ctrl+shift+6 to set mark no-port-forwarding,no-agent-forwarding,no-X11-forwarding,command="echo 'Please login as the user "ubuntu" rather than the user "root".';echo;sleep 10"\

TODO

• generate separate ssh key for heketi user
• generate separate ssh key for ansible user
• gluster inventory could be simplified
• try to use virtual disk rather than mounting an external disk (this is for fully independent from cloud providers)
