federation create_mapping signature and V9 wrapper incorrect

[Henry Nash]

The original abstract signature for the create_mapping() driver method was wrong in the federation manager in Liberty. This was then inadvertently copied to the V9wrapper when we created the V9 driver in Mitaka. This would cause V8 federation drivers to fail with Mitaka. The legacy testing did not cover all the CRUD tests, which is why this was not discovered when the V9 driver was created.

    Fix incorrect signature in federation legacy V8 wrapper

    The abstract signature for the create_mapping driver method in the
    Liberty V8 driver interface was wrong, which was then inadvertently
    used to create the V9 wrapper. This fixes that issue and adds attitional
    legacy tests to ensure the federation V8 CRUD operations are covered.

    There are numerous other inconsistency in the docstrings of the
    federation abstract methods, these are resolved in a follow on patch.
