Comment 6 for bug 1171601

The "use_tpool" option (formerly "dbapi_use_tpool") isn't anymore part of Nova with commit [1]. "oslo.db" on the other hand is still using this [2]. Therefore I'm removing "nova" as affected project but add "oslo.db" instead.

Unfortunately the eventlet fix is sill open [3].
