Use supercedent manager in post
Update the post (and promote) pipelines to use the supercedent
pipeline manager.  This will cause only the latest versions of
artifacts to be published, rather than having multiple jobs
racing.
This pipeline runs jobs that operate after each change is
merged. Queue items are identified by the abbreviated hash (git
log --format=%h) of the merge commit.
