Introduce both the launchSecurity XML and parser classes. While at it,
add launchSecurity as a property instance to the Guest class too.
The parser requires the 'type' argument to be mandatory since in the
future it will determine different code paths, therefore
'--launchSecurity foo=bar' is incorrect.
