1. Reverted generated directory logic.
2. "/tmp/drill/udf" + cluster-id is not good idea, since local udf
directory has similar location as remote. And remote directory is generated as
cluster-id + /udf. So I suggest to keep it as is. Local registry is returned to
use its previous composition logic.
3. Removed "cluster-temp-dir", we don't need it for now.
