Use commit eaab5fae2502198e9fa57d0d90a7204a2bd83b16: Merge "sort options to make --help output prettier" (Wed Feb 13 12:52:14 2013 +0000) Add processutils to quantum since impl_zmq depends on them. Drop notifier.list_notifier that is not present in oslo. Change-Id: I91d9ec05481b8c24da9fbee1ad4706ff56a3b7aa Fixes: bug #1116290
