Move log_handler from oslo-incubator to oslo.messaging and include unit tests. This patch also adds an additional test case from the original version in oslo-incubator. Originally, the test case only checked to make sure the notification was not sent. Now a positive test case exists to test both paths. bp graduate-notifier-log-handler Co-Authored By: Ben Nemec <bnemec@redhat.com> Change-Id: I9ea051ec7e3614579341a31d8dc1c13d9514b8a9
