[FEATURE REQUEST] Add option to set default console viewer for vms

[GZTime]

Currently, vm can only use noVNC as the default console viewer.

I checked the source code and the xtermjs property of this component can be set, so is it possible to add the option of a default console viewer to the vm options (similar to what is configured in the datacenter).

In `www/manager6/qemu/Config.js`:

```js
if (caps.vms['VM.Console'] && !template) {
me.items.push({
title: gettext('Console'),
itemId: 'console',
iconCls: 'fa fa-terminal',
xtype: 'pveNoVncConsole',
vmid: vmid,
consoleType: 'kvm',
// xtermjs: ...?
nodename: nodename,
});
}
```

If your VM is configured correctly with the serial console, xterm.js is automatically used as the default viewer. The same applies to Spice. And what kind of guest operating system is it?

You can see my ubuntu has enabled getty@ttyS0, but the default console still is noVNC, I can't switch it to xterm.js even if I set the Display to None in hardware (which causes connection error instead).

Where could we see this? You cannot see the default in your screenshot. I conccur to @fireon, this is exactly the behaviour I also see when clicking just on console (not on the down-arrow)
