Title: gh-1874 Configmgr - Enable deletion of attributes

- In XML view clicking 'Delete' from the context menu,
deletes the attribute and its' value.
- No validation is done on the delete.
- Context menu 'Delete' is available only for attributes.
- Only attributes that can be specified using an unambiguous XPath will
succeed.
- Deleted optional attributes appear in red.
- Context menu closes when clicking off the menu.
- After delete, nested XML Tree View refreshes to previous location.
