docs: Get a value from settings store, this is the prefered way to access::
  
              >>> from dynaconf import settings
              >>> settings.get('KEY')
  
          :param key: The name of the setting value, will always be upper case
          :param default: In case of not found it will be returned
          :param cast: Should cast in to @int, @float, @bool or @json ?
          :param fresh: Should reload from loaders store before access?
          :param dotted_lookup: Should perform dotted-path lookup?
          :return: The value if found, default or None
