vmware: Use cookiejar from oslo.vmware client directly

With changing the SOAP library backing oslo.vmware [1], the cookiejar of
a session must be accessed differently. Therefore, oslo.vmware
introduced a property on the client to abstract this change away. This
commit uses the new place to access the attribute.
