Adding the support for snapshot/restore feature for all supported vhost-user devices. The complexity of vhost-user-fs device makes it only partially compatible with the feature. When using the DAX feature, there's no way to store and remap what was previously mapped in the DAX region. And when not using the cache region, if the filesystem is mounted, it fails to be properly restored as this would require a special command to let the backend know that it must remount what was already mounted before.
