class CloudInitPickleMixin:
    """Scaffolding for versioning of pickles.

This class implements ``__getstate__`` and ``__setstate__`` to provide
    lightweight versioning of the pickles that are generated for classes which
    use it.  Versioning is done at the class level.

The current version of a class's pickle should be set in the class variable
    ``_ci_pkl_version``, as an int.  If not overriden, it will default to 0.

On unpickle, the object's state will be restored and then
    ``self._unpickle`` is called with the version of the stored pickle as the
    only argument: this is where classes should implement any deserialization
    fixes they require.  (If the stored pickle has no version, 0 is passed.)

This adds a ``_ci_pkl_version`` attribute to ``self.__dict__`` and
        returns that for serialisation.  The attribute is stripped out in
        ``__setstate__`` on unpickle.

The value of ``_ci_pkl_version`` is ``type(self)._ci_pkl_version``.

        removes the pickle version from the stored state, restores the
        remaining state into the current instance, and then calls
        ``self._unpickle`` with the version (or 0, if no version is found in
