Update ncclient examples

- added optional parameter host for copy_config, get_config
  and edit-config.
- added basic tests for interfaces:
  - loopback interface
  - af-packet interface
  - tap interface
- added diff_xml.py to find differences between two sets of config.
  It supports both full xml comparison and comparison based on xPath
- added example diff between running and candidate config (interfaces)
- fixed formatting and namespaces
