For Move operation YADE should delete sub directories from the source_dir if parameter remove_sub_dirs=true

Current Situation

• As of now BY DESIGN for operation=move and recursive=true YADE moves the files but keeps empty sub directories
• YADE Profile

  [MoveRemoteSFTP2LocalhostRecursive]
  file_spec              = ^rgp.*\.txt$
  operation              = move
  recursive              = true
  ;;
  source_host            = homer.sos
  source_protocol        = sftp
  source_port            = 22
  source_user            = test
  source_ssh_auth_method = publickey
  source_ssh_auth_file   = ${HOME}/.ssh/id_rsa
  source_dir             =  ${HOME}/data/from_homer/rgp
  ;;
  target_dir             = ${HOME}/data/to_galadriel
  target_host            = localhost
  target_protocol        = local
  

• Before JADE move operation

  test@homer:~/data/from_homer/__rgp> ls -lrt *
  +--> c/rgp300.txt
  +--> b/rgp200.txt
  +--> a/rgp100.txt
  

• After JADE move operation

  test@homer:~/data/from_homer/__rgp> ls -lrt *
  +--> c/
  +--> b/
  +--> a/
  

Desired Behavior

• YADE should have a new parameter e.g. remove_sub_dirs=true/false in conjunction with operation=move
• If parameter remove_sub_dirs=true YADE should also delete the sub directories under the source_dir
