v3 controller does not check for required field

[gordon chung]

when creating item, 500 Internal Server Error returned when no name given. Should return 400 Bad Request code.

ie. curl -X 'POST' -H 'X-Auth-Token: openstack1' -H 'Content-Type: application/json' -d '{"project":{"description":"est"}}' http://localhost:35357/v3/projects
