Subject: libraries/libvirt: Added soft_restart() to rc.libvirt

With this patch, "rc.libvirt soft_restart" will kill and restart the
libvirt services without affecting any running virtual machines.
This has been a necessity for the SBo infrastructure given our recent
struggles with libvirt losing dbus connectivity without explanation.
