catalog-diff compiles a host's catalog in two environments and diffs them to validate puppet-prod changes before merge, which means compiling catalogs on behalf of other nodes via POST /puppet/v4/catalog. The compilers run the image default auth.conf, where that endpoint is denied.
- add a compiler auth.conf allowing catalog-diff.main.unkin.net to POST /puppet/v4/catalog
- add a pre-default entrypoint script seeding it into conf.d, failing hard if the source is absent
- mount both onto the compiler deployment via configMapGenerator
