    Fix permissions for the Nova lock directory in systemd

    The directory set as `lock_path` in `nova.conf` must be created with
    the nova system user as its owner, otherwise the VIF plugin would fail
    to acquire a lock when launching an instance.

    Here we set up systemd to create this directory with correct owner and
    permissions, besides moving its path to a `nova_lock_path` variable.

    Apparently, the `/var/lock/{{ item.value.service_name }}` directory,
    which is also created by `nova-systemd-tempfiles.j2`, is not needed at
    all. But as this patch is intended to be backported to a stable release,
    we keep it by now to avoid any unforeseen issues.
