Too much logging to system out when using webapp

[jacodg]

Describe the bug
The Frank!Runner is now using the Frank!Flow webapp. This generates a lot of logging in the Tomcat window when you go to https://localhost/frank-flow/ I think this is caused by the CXF logging not being configured. I did a small test locally by copying slf4j-api and slf4j-simple jars from ibis-ladybug-test-webapp to frank-runner\build\apache-tomcat-9.0.60\webapps\frank-flow\WEB-INF\lib and adding simplelogger.properties to frank-runner\build\apache-tomcat-9.0.60\webapps\frank-flow\WEB-INF\classes with:

org.slf4j.simpleLogger.log.org.apache.cxf.interceptor=WARN

This seems to work but maybe we want you use log4j? See https://github.com/ibissource/frank-flow/blob/master/frank-flow-webapp/src/main/resources/log4j2.xml also. I think the name "INVALID CONFIGURATION" needs to be changed or implies that it is work in progress?
