[Qemu-devel] [RFC 24/24] avocado_qemu: Add a few VNC related tests

[Eduardo Habkost <ehabkost@redhat.com>]

From: Cleber Rosa <crosa@redhat.com>

These exercise the basics of firing up QEMU with and without
a VNC device, and attempting to set the password when a VNC
device and password is given (or not).
