A temporary helper which emulates oslo.messaging.Notifier.
|
|
|
|
This helper method allows us to do the tedious porting to the new Notifier API
|
|
as a standalone commit so that the commit which switches us to oslo.messaging
|
|
is smaller and easier to review. This file will be removed as part of that
|
|
commit.
