Fix release of resources created by Tempest
Fix release of resources created by Tempest

Tempest fails to release created resources by Manila using dynamically
created tenant. It is caused by changed order of deletion,
where Tempest started execute dynamic tenant deletion prior to
release of Manila resources within this tenant.
So, fix it by changing order of resource release in Manila base class.
