In Ib51e2839f9035d0cc0e3f459939d9f9003a8c810, oslo.messaging is introducing a new group for the notifiction options. This review is the minimum needed to support both old and newer oslo.messaging versions. (In other words, next oslo.messaging release will break ceilometer unless we work around for the new option group) Change-Id: I4765b3b9627983a245aa5521a85ad89e83ab8551
