Improvement for log handling

From this version it is possible to make some basic configuration for the log settings from inside the PIP Configurator. The changes in the log settings will be saved directly in the log4j2.xml file. For any advanced configuration, the settings are made directly in the log4j2.xml file.

Export and import of log configuration

When exporting a policy with policy specific logging, the corresponding log settings in the log4j2.xml file will be exported as well. 

When importing a policy with policy specific logging, the log setting will appear as a separate object in the list of import objects.
