Revert "Remove tempest from list of projects that direct release."

This reverts commit e127f9a88aee7512c97e92b9eb07a9632154616a.

After a recent discussion during the QA weekly irc meeting it was
decided that that tempest bugs should be marked as fixed released
immediately after the fix is merged.
