Make max dataization log level configurable

[mximp]

In order to simplify debugging let's make below hardcoded value configurable via jvm property -Dmax.dataization.log. It must be defaulted to 4.

Dataized.java

if (Dataized.LOGGER.isLoggable(Level.FINE)
                && Dataized.LEVEL.get() < 4
            )

Budget: 30min
