Will this make the `setLogLevels` complicated for the user? For example, if
user wants to change several log levels for the entire application. He also
wants to set a particular logger for the runnable. He will have to have to pass
in the entire map to `setLogLevels(runnableName, logLevelsMap)`. Is it good to
do so?
