This gives us an empty check queue on every project so that zuul will
report syntax and config errors on push to all projects in the opendev
There are no pipelines defined in the opendev tenant. This makes
it exceedingly hard to, you know, put jobs in them. Also add
noop jobs for this repo so that we can land changes without
force merging. And add a license file to make it clear that
content is Apache.
These are copied from the zuul tenant.
