    Lower ObjectVersionChecker logging to DEBUG level

    The ObjectVersionChecker fixture is logging object
    comparison at INFO which in some tests can blow up
    the subunit output stream capture parser (see nova
    bug 1813147). This change drops the logging level
    to DEBUG which can be enabled using the OS_DEBUG
    environment variable found in oslotest.
