Comment 3 for bug 1606843

Currently, timeout exception has been handled and converted to internalerror eception in the following code:
http://git.openstack.org/cgit/openstack/senlin/tree/senlin/drivers/openstack/sdk.py#n70

So physical_id==None means exception happened during Profile.create_object and it was not caught correctly. Maybe need to dig more here to find the reason if it happens.
