fix(console): a VNC console stays open while its screen does not change

Browse source 
nginx ends a proxied websocket that sends nothing for 60 seconds, and the
VNC console sends nothing while the VM's screen stays the same: an idle
console, an installer's progress screen, closed after a minute and had to
be connected again. novncd now pings the browser every 30 seconds. The SSH
tunnel of an SSH compute sends a keepalive as often, for a firewall on the
way that ends idle connections.
