    More useful message when using direct driver import

    In the Liberty release, we switched to using entrypoints for
    specifying the driver or auth plugin. The deprecation message
    didn't mention the driver name that was specified, nor did it
    mention where to look for the expected names, so it was not
    user friendly.
