S(s]A helper method to execute JSON-Schema Validation.

    This method checks the request version whether matches the specified max
    version and min_version. It also takes a care of legacy v2 request.

    If the version range matches the request, we validate the schema against
    the target and a failure will result in a ValidationError being raised.

    :param schema: A dict, the JSON-Schema is used to validate the target.
    :param target: A dict, the target is validated by the JSON-Schema.
    :param min_version: A string of two numerals. X.Y indicating the minimum
                        version of the JSON-Schema to validate against.
    :param max_version: A string of two numerals. X.Y indicating the maximum
                        version of the JSON-Schema to validate against.
    :param args: Positional arguments which passed into original method.
    :param kwargs: Keyword arguments which passed into original method.
    :param is_body: A boolean. Indicating whether the target is HTTP request
                    body or not.
    :returns: A boolean. `True` if and only if the version range matches the
              request AND the schema is successfully validated. `False` if the
              version range does not match the request and no validation is
              performed.
    :raises: ValidationError, when the validation fails.

Strip the additional properties from the req.GET.

    This helper method assumes the JSON-Schema is only described as a dict
    without nesting. This method should be called after query parameters pass
    the JSON-Schema validation. It also means this method only can be called
    after _schema_validation_helper return `True`.
