The cinder-common package in Ubuntu and Debian used to provide
the additional config file for tgt daemon to allow the daemon to
expose volumes managed by cinder. However that config file is no longer
provided by the package since Wallaby release and now creating
attachment fails with the following warning in cinder-volume.log.
```
Failed to create iscsi target for Volume ID: volume-<UUID>. It could be
caused by problem with concurrency. Also please ensure your tgtd config
file contains 'include /var/lib/cinder/volumes/*'
```
This change ensures the include line is added in Ubuntu/Debian to fix
the error.
