Lacking an option to reduce the verbosity of some classes

[ctchervenkov]

The run methods for some classes, e.g. PublicTransitMapper, can be very verbose at times. However, there currently is no option to toggle this off.

This would be nice, for example, when running the methods as a part of a CI pipeline to not overfill the log files.

In the master branch (23.4-SNAPSHOT), we already switched to Log4j 2 for logging and we will create a release shortly after MATSim 15.0 is released next week.
Log4j 2 can be configured in multiple ways. Without having tested it, I would try to pass a custom log4j2.xml file to it via the -Dlog4j2.configurationFile property.
