Agent HardwareManager loading always loads GenericHardwareManager

[Russell Haering]

The HardwareManager loading logic in the Ironic Python Agent attempts to load the most suitable implementation found by stevedore, but sorts them in the wrong order so always ends up loading the GenericHardwareManager.

    Fix HardwareManager loading order bug

    The agent attempts to sort the HardwareManager implementations found
    by stevedore in order of suitability. This patch fixes a bug in the
    sorting order that caused the GenericHardwareManager to always be
    loaded.

    Fixes bug 1327923
