This change adds a constraint to the
"/var/lib/libvirt/qemu/save" directory state check and list commands
so that should the dir not exist and not be created by the libvirt
startup process the role can carry on with the subsequent linking
of "/var/lib/libvirt/qemu/save" to "{{ nova_libvirt_save_path }}".
