With libvirt-python >= 4.4.0 and libvirt < 4.4.0 we would receive
libvirt.libvirtError exception because the python binding knows about
the function but it's not supported by libvirt. However, in case that
the python binding is older then 4.4.0 it will raise AttributeError
because the function is not implemented in python binding as well.

Let's download and install the pre-installable drivers, if they're
available.
The reason we're only dealing with pre-installable drivers here is that
post-installable drivers would have to keep the unattended is available
accross reboots, resulting in a file that can't be cleaned up at this
point.

Similarly to what has been done for _device_filter(), let's add
"extra_args" parameter to support_* methods so we can pass them down to
_device_filter().
Only supports_virtio* methos would actually need the extra argument, but
let's be consistent here and add it to all supports_* methods.

Let's add "extra_devs" to _device_filter() so we can pass a list of
devices which can be used by an OS but are not part of the distro / OS
itself.
By doing this, we also expand the _device_filter() check and take those
into account when they're passed.
That's exactly the case of pre-installable drivers for Microsoft
Windows.

The post-installable drivers provided by osinfo-db are merely agents,
which are not a blocker for an installation to succeed using virtio &

Let's add this method as a counter part of supports_unattended_drivers()

virt-install and are able to perform installations of MSIs.

supported_unattended_drivers() was originally added as a way to tell
whether a guest could support pre & post installable drivers.
This is wrong for two reasons:
- virt-install cannot deal with post-installable drivers/agents;
- pre-installable drivers are the only ones needed in order to perform
an unattended installation taking advantage of virtio-win drivers;
Knowing that, let's only check for pre-installable drivers in
supported_unattended_drivers().

osinfo-db may contain files pointing to local paths, which will have the
format 'file:///usr/share/...'.
With the current code, virt-install would just bail as it doesn't
understand the 'file://' schema. Let's start using urllib (which is
already imported in the very same file) and parse the URL so both
'file:///usr/share/...' and '/usr/share/...' would work.

QEMU version 2.12.1 introduced a performance feature under commit
be7773268d98 ("target-i386: add KVM_HINTS_DEDICATED performance hint").
Support for this performance hint was added in libvirt 5.7.0 by commit
cb12c59dac04 ("qemu: support for kvm-hint-dedicated performance hint").
This patch extends virt-install's existing --features option to insert the
appropriate XML into the guest definition if this feature is specified
on the command line.
E.g. --features='kvm.hint-dedicated.state=on' would result
in the following XML:
<features>
...
<kvm>
<hint-dedicated state='on'/>
</kvm>
...
</features>

Windows' unattended installations have more than one installation script
in order to perform a "post" installation of some drivers
(spice-guest-tools, actually).
In order to do so, let's:
- Change unattended::_lookup_rawscript() to return a list of scripts;
- And also rename it to _lookup_rawscripts();
- Change unattended::prepare_install_script to return a list of scripts;
- And also rename it to prepare_install_scripts
- Change installer::_prepare_unattended_data() to deal with a list of
scripts;
- And also do the "renaming" changes accordingly;
- Change installertreeinfo::_prepare_unattended_data() to deal with a
list of scripts;
- And also do the "renaming" changes accordingly;
- Mind that this change is not exactly needed as Linux unattended
installations have only one install script. However, the change has
been done ir order to be consitent with the changes done in the
installer;
- Change installertreeinfo::_prepare_kernel_args() to deal with a list
of scripts;
- And also do the "renaming" changes accordingly;
- As the changes above, this one is not exactly needed for the very
same reason;
