virt.libvirt_vm: Pretty print virt install command

Just as we made with the kvm based class, reformat
the command that is going to be printed to the logs,
making it more readable. With the patch, a virt-install
command line now looks like:

virt.step_editor: cleanups and make it independent of autotest

Do the usual cleanups (try to remove as much as possible
use of reserved symbols), and also, reduce cross dependency
on other autotest libs. step editor is useful even outside
of the autotest realm, so this paves the way for external
usage of this application.
