This work is preparing the field for adding and using metadata.libosinfo
in GNOME Boxes (in a similar way that's already done for virt-manager)
so we can have a cross-app schema for tracking libosinfo OS ID in the
domain <metadata> XML.
The tests added are from real cases as:
- current Boxes' metadata (so, we ensure we won't break anything there);
- the new Boxes' metadata.libosinfo;
- Nova's XML example;

New subject: [libvirt] [glib PATCH 1/2] object: Also add the ns to the node's children
With the current code, we can only create a custom XML that looks like:
<metadata>
<boxes:gnome-boxes xmlns:boxes="https://wiki.gnome.org/Apps/Boxes">
<os-state>installed</os-state>
<media-id>http://centos.org/centos/7.0:0</media-id>
<media>/home/fidencio/Downloads/CentOS-7-x86_64-DVD-1804.iso</media>
</boxes:gnome-boxes>
</metadata>
Although it works well for some use cases, there are use cases where
we'd like to have something a bit more complex libosinfo or nova
examples:
<metadata>
<libosinfo:libosinfo
xmlns:libosinfo="http://libosinfo.org/xmlns/libvirt/domain/1.0"...
<libosinfo:os id="http://fedoraproject.org/fedora/17"/>
</libosinfo:libosinfo>
<nova:instance xmlns:nova="http://openstack.org/nova/instance/1">
<nova:flavor name="m1.small">
<nova:memory>512</nova:memory>
<nova:disk>10</nova:disk>
</nova:flavor>
</nova:instance>
</metadata>
And for the latter case we'd have to go through the node's children and
also set the namespace for each children.

New subject: [libvirt] [glib PATCH 2/2] domain: Introduce gvir_config_domain_set_custom_xml_ns_children()
gvir_config_domain_set_custom_xml_ns_children() basically has the same
functionallity as gvir_config_domain_set_custom_xml() but also sets the
namespace to the nodes' children.
