Does Unraid have any plugin or functionality to create and configure VM programatically?
I need to create system where virtual machines are created on demand .

Not that I'm aware of. You could look at some of spaceinvader one's recent work, he is doing something along the same idea.

You can create an XML and pass that into virsh to create VMs and destroy them.

function virsh_device_by_bus($action, $vmname, $usbbus, $usbdev)
{
	$usbstr = '';
	if (!empty($usbbus)) 
	{
		$usbbus=ltrim($usbbus, "0");
		$usbdev=ltrim($usbdev, "0") ;
		$usbstr .= "<hostdev mode='subsystem' type='usb'>
	<source>
	<address bus='${usbbus}' device='${usbdev}' />
	</source>
	</hostdev>";
	}
	$filename = '/tmp/libvirthotplugusbbybus'.$vmname.'.xml';
	file_put_contents($filename,$usbstr);
	

return shell_exec("/usr/sbin/virsh $action-device '$vmname' '".$filename."' 2>&1");


#echo "Running virsh ${COMMAND} ${DOMAIN} for USB bus=${BUSNUM} device=${DEVNUM}:" >&2
#virsh "${COMMAND}" "${DOMAIN}" /dev/stdin <<END
#<hostdev mode='subsystem' type='usb'>
#  <source>
#    <address bus='${BUSNUM}' device='${DEVNUM}' />

#END

Here is some PHP code that I use for hotplugging USB devices into a VM.

Thanks a lot. That gives me the start I need.
Does Unraid detect these virsh created machines and show them in server UI?

I believe they should, but can't safe 100% for sure as not tested it myself.
