This is a mechanically generated patch to complete step 1 of moving
the zuul job settings out of project-config and into each project
repository.
Because there will be a separate patch on each branch, the branch
specifiers for branch-specific jobs have been removed.
Because this patch is generated by a script, there may be some
cosmetic changes to the layout of the YAML file(s) as the contents are
normalized.
