    Downgrade log for keystone verify client fail

    Under some circumstances the keystone verify process might fail
    but we are able to proceed because it's client setting error,
    so we don't need to report an exception log in the log file to
    confuse admin, instead, use an info log.

    In the reported bug, the issue is that nova is configured for
    the 'internal' identity endpoint but the nova code does not
    pass an interface, so KSA defaults to 'public' which fails.
    This is fixed with I2204c8bed8936d5bed0f410284d2a563f84e7100
    but not something we can backport, so this is a simple change
    to make the logging less annoying.
