CLI: Add commands to handle attachments

Browse source 
* Add commands to manipulate entry attachments from the CLI
* Closes #4462

* Add the following commands:
  attachment-export: Exports the content of an attachment to a specified file.

  attachment-import: Imports the attachment into an entry. An existing attachment with the same name may be overwritten if the -f option is specified.

  attachment-rm: Removes the named attachment from an entry.

* Add --show-attachments  to the show command
