#check_directory_key(directory_key) ⇒ Object

check_directory_key have two functions:

  1. trim the directory_key suffix ‘/’

  2. checking whether the directory_key is a bucket. If so, it will return directly to avoid to create a new redundant folder named with directory_key. This point will be applied to multi-bucket and make bucket as a directory scenario.
