keystone logs for unit tests are too verbose

[Henry Nash]

The current full jenkins run comes close to blowing the 50Mb limit we set for "success", meaning that minor changes can tip the logging over this limit and tests "fail". Once of the major culprits is that we log every time (for every test) when someone subscribes to a callback notification. This seems overzealous and wasteful of electrons.

We should set the default notification log level to INFO in the tests/core.py to suppress this.

    Reduce unit test log level for notifications.

    The current debug level of notifications causes unit test debug
    files to be very large. This patch reduces the default log level
    for notifications to INFO. This single change reduces the size
    of the debug file by 20Mb (or 38%).
