[ADF-1774] Extend "Create Folder" and add "Edit Folder" dialogs to ADF (#2585)

* [ADF-1774] Extend "Create Folder" and add "Edit Folder" dialogs to ADF

- added create and edit folder directives and used them inside the demo-shell file component
- added FolderDialogComponent for edit/create actions with name validators: forbidSpecialCharacters, forbidEndingDot and forbidOnlySpaces
- updated the translation files
- added unit tests for the new components
- removed the CreateFolderDialogComponent and its usage inside demo-shell
- added documentation files for FolderCreateDirective and FolderEditDirective

* [ADF-1774] fix messed up translation files because of previous commit

* [ADF-1774] changes required on code review comments
