      Removes locally cached copies of media attachments from other servers.

      The --days option specifies how old media attachments have to be before
      they are removed. It defaults to 7 days.

      With the --background option, instead of deleting the files sequentially,
      they will be queued into Sidekiq and the command will exit as soon as
      possible. In Sidekiq they will be processed with higher concurrency, but
      it may impact other operations of the Mastodon server, and it may overload
      the underlying file storage.
