imaging: PXE proxy - default menu item processing

* added a detecting of selecting the menu entries when backup or restore
  selected (based on parsing of log messages, so little bit ugly...)
* default menu entry is now readed from database, which overrides
  default menu item selecting from imaging client.
imaging: sort the remaining menu items if an item removed
imaging: All menu items sorted during service start
imaging: [fix] menu items sort
imaging: [revert] do not sort menu items on start
