[libvirt-ci PATCH 11/12] config: Move the virt-install settings from install.yml to the config

[Erik Skultety]

Looking into the future where we're able to generate cloudinit images,
we'll need to configure some of the install options which is currently
not possible without editing the install.yml group vars file within the
repository. That is suboptimal, so let's move the install options to
the global config under the 'install' section so that further tweaking
is possible (but explicitly discouraged at the same time).
