def path_helper(self, path=None, operations=None, **kwargs):

Works like a apispec plugin
    May return a path as string and mutate operations dict.

:param str path: Path to the resource
:param dict operations: A `dict` mapping HTTP methods to operation object. See
    https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.2.md#operationObject
:param kwargs:
:return: Return value should be a string or None. If a string is returned, it
is set as the path.
