This commit updates the entire CRITs codebase to be compatible with Python 3:

- Used modernize tool to automatically convert Python 2 code to Python 3
- Added __future__ imports for absolute_import and print_function
- Updated print statements to use function syntax
- Fixed exception handling to use modern syntax (except Exception as e)
- Updated dictionary iteration methods to use six compatibility library
- Fixed remaining .iterkeys() usage to use six.iterkeys()
- Updated xrange to range in example services
- Updated requirements.txt for Python 3 compatibility:
  - Set Django version to >=1.11,<2.0
  - Removed wsgiref (built-in for Python 3)
  - Changed pycrypto to pycryptodome (Python 3 compatible)
- Added six library imports for Python 2/3 compatibility

The codebase now supports Python 3 while maintaining compatibility
through the six library for transitional period.
