refactor(console): one keys menu module for both VNC console pages

Browse source 
The lite and the full console page each carried the same 150 lines that
send key combinations (Ctrl+Alt+Del, Ctrl+Alt+F1..F12, Alt+Tab, ...). They
now import static/js/console_keys.js, which binds the menu to the page's
RFB connection.
