[PATCH v7 8/8] Acceptance test: add "boot_linux" tests

[Cleber Rosa <crosa@redhat.com>]

This acceptance test, validates that a full blown Linux guest can
successfully boot in QEMU.  In this specific case, the guest chosen is
Fedora version 31.

 * x86_64, pc and q35 machine types, with and without kvm as an
   accellerator

 * aarch64 and virt machine type, with and without kvm as an
   accellerator

 * ppc64 and pseries machine type

 * s390x and s390-ccw-virtio machine type

The method for checking the successful boot is based on "cloudinit"
and its "phone home" feature.  The guest is given an ISO image
with the location of the phone home server, and the information to
post (the instance ID).  Upon receiving the correct information,
from the guest, the test is considered to have PASSed.

This test is currently limited to user mode networking only, and
instructs the guest to connect to the "router" address that is hard
coded in QEMU.

To create the cloudinit ISO image that will be used to configure the
guest, the pycdlib library is also required and has been added as
requirement to the virtual environment created by "check-venv".

The console output is read by a separate thread, by means of the
Avocado datadrainer utility module.
