Remove old oslo.messaging transport aliases
Remove old oslo.messaging transport aliases

Those are remnants from the oslo-incubator times. Also, oslo.messaging
deprecated [1] transport aliases since 5.2.0+ that is the minimal
version supported for stable/newton. The patch that bumped the minimal
version for Ironic landed 3 months+ ago, so we can proceed ripping
those aliases from the code base.
