Description of feature: There should exist a way to delete files from a specific user. Something like "prosodyctl http_file_share purge_all JID" The user address is already stored on upload time for the quotas feature. So maybe this could somehow be reused. Motivation: If a user requests deletion of all their data according to EU law, it should be possible to comply, without waiting for the automatic deletion time of the service. ---- A bonus feature could be to be able any specific file. e.g. if it is against the server rules or the law.
