[QEMU] add cluster QEMU
- Add action
add_to_local_conf_opt, which behaves likeadd_to_local_confbut doesn't append anything tolocal.confif the value set is empty. - Support unquoted empty values in .config file (fix)
- Add cluster QEMU which contains the QEMU runtime configuration options used to generate the
.qemuboot.conffiles.
The cluster is associated to action add_to_local_conf_opt instead of add_to_local_conf to avoid bloating the local.conf and to leave useful default values set.
