Wants to do the opposite of P481 (add the new annex folder) P481 is a diff of
what's in production against what's in swh-site (so wants to remove the manual
installation of that new folder). We want to keep that new folder so i
puppetized it.
As in commits:
- annex_web: Explicit possible issue in current annex setup
- annex: Add missing instructions
As far as the documentation or the execution goes, there is no pre-defined dsl
to set those so fallback to use the custom_fragment instead.
