    Use from_dict to load context params

    The context objects accepts and ignores unknown keyword arguments. This
    was to allow it to handle the deserialization of parameters it didn't
    understand from the base class' to_dict method. This will make it
    difficult to pass unknown attributes to the base class so fix the
    from_dict method to only accept params it knows about.
