Various improvement to enhance portability:

  - Use parsable Configuration file respective ConfigParser module
  - Update documentation with sample of configuration file
  - Create entry_point for console named web_checker_utility

 Utility able to call wget and varnishlog to extract Headers and return all failures
 according expected caching policy.
 
-This utility is configurable through a dictionnary like
-   configuration = {'url': 'http://www.example.com',

-                                   'Cache-Control': ('max-age=300', 'max-age=3600',),
-                                   'Vary' : ('Accept-Language, Cookie', 'Accept-Language,Cookie'),
-                                   'Expires': True,
