Since as of #3980 (bug 1470622) the frontend no longer calls the
`/retrigger/` `/cancel/` or `/cancel_all/` Treeherder APIs.
Whilst looking at the pulse related fixtures, I spotted that the
`mock_message_broker` fixture was already unused.
Since testing Django management commands involves running them and
checking the log output this provides us with a way to test message
reading functionality while also reducing those scripts down to a simple
configuration.
The PulsePublisher class was built for extensibility, providing lots of hooks
for customisation. However we only had one subclass in use since its
introduction: TreeherderPublisher. This reduces the concrete class into a
single function which publishes the given message. In doing so all
configurability has been removed, since it was unused.
