  Move the given folder under a new parent folder or under the organization.
  Exactly one of --folder or --organization must be provided.

  This command can fail for the following reasons:
      * There is no folder with the given ID.
      * There is no parent with the given type and ID.
      * The new parent is not in the same organization of the given folder.
      * Permission missing for performing this move.

  ## EXAMPLES

  The following command moves a folder with the ID `123456789` into a
  folder with the ID `2345`:

    $ {command} 123456789 --folder=2345

  The following command moves a folder with the ID `123456789` into an
  organization with ID `1234`:

    $ {command} 123456789 --organization=1234
