    """set up the provision.py module for this dialect.

        For dialects that include a provision.py module that sets up
        provisioning followers, this method should initiate that process.

        A typical implementation would be::

            @classmethod
            def load_provisioning(cls):
                __import__("mydialect.provision")

        The default method assumes a module named ``provision.py`` inside
        the owning package of the current dialect, based on the ``__module__``
        attribute::

            @classmethod
            def load_provisioning(cls):
                package = ".".join(cls.__module__.split(".")[0:-1])
                try:
                    __import__(package + ".provision")
                except ImportError:
                    pass
