ObjectVersionChecker should not be logging at INFO level

[Matt Riedemann]

This was found while debugging a nova bug that shows up intermittently in py35 unit test runs:

https://bugs.launchpad.net/nova/+bug/1813147/comments/25

The ObjectVersionChecker fixture in oslo.versionedobjects is logging at INFO level which can be a lot of output in certain nova tests and blow up the subunit parser with the output stream capture.

There doesn't seem to be a great reason to need to log at INFO level in a test fixture, so we should probably drop that to DEBUG which most tests shouldn't be capturing at that level unless configured to do so, e.g. the OS_DEBUG environment variable found in oslotest.

    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.
