Merge lp:~mvo/launchpad/add-cnf-metadata-to-release-file into lp:launchpad

[Michael Vogt]

This tiny MP adds code to launchpad to add command-not-found metadata in the archive to the Release file so that this metadata can be fetched via `apt update`. Getting the metadata to this dir will require an extra MP for ubuntu-archive-publishing.
