tracking OS installer kernel argument for URL installs
virt-install knows that modern fedora/rhel/etc need inst.repo=$URL on the kernel command line if doing --location URL installs. suse needs install=
URL similarly. #26 (closed) tracks wiring this up for unattended installs, but it would be nice if osinfo-db tracked this data in some way that virt-install can use it for non-unattended installs as well, so we can eventually drop the inst.repo/install hardcoding.
