Clear cache job

[alec-c4]

Hi!
I'd like to suggest background task with small improvements for clearing cache

class ClearAttachmentCacheJob < ApplicationJob
  queue_as :default

  def perform(*args)
    cache_storage = Shrine.storages[:cache]

    if cache_storage.instance_of?(Shrine::Storage::FileSystem)
      cache_storage.clear! { |path| path.mtime < Time.now - 7*24*60*60 } # delete files older than 1 week
    elsif cache_storage.instance_of?(Shrine::Storage::S3)
      cache_storage.clear! { |object| object.last_modified < Time.now - 7*24*60*60 } # delete files older than 1 week
    end
  end
end

Very nice. I personally do it via a bucket life cycle rule. Basically i tell aws:

Clear all caches older than 1 week.
