[one-users] sunstone noVNC - connect timeout

[Hector Sanjuan]

Hello, if the browser solution doesnt fix it, try running python  
/usr/share/one/noVNC/utils/websockify 5904 node3:5904 by hand and then  
clicking on the vnc icon in sunstone. Console should throw some output as  
the connection comes it and maybe a better description of why it fails.
