Unity: force delete lun by default

Browse Source 
The option `force_delete_lun_in_storagegroup` was set to `False` by
default before. Customers should change it to `True` in `cinder.conf` to
make sure luns can be deleted even when they are still in storage
groups.

This fix enables the option's default value to `True`.
