  Updates the given folder with new folder name.

  This command can fail for the following reasons:
      * There is no folder with the given ID.
      * The active account does not have permission to update the given
        folder.
      * The new display name is taken by another folder under this folder's
        parent.

  ## EXAMPLES

  The following command updates a folder with the ID `123456789` to have
  the name "Foo Bar and Grill":

    $ {command} 123456789 --display_name="Foo Bar and Grill"
