Test logging fix, by default log4j2 looks for log4j2.properties file (linkedin#2181)

`log4j.properties` files are ignored in the test resources, after renamed, finally I was able to change the loglevels while unit/integration testing.

I'm not sure if it was the issue on issue linkedin#2152, but this would be the fix for tests. Prod should work with the log4j.properties file as that is passed with -Dlog4j.configurationFile java opt
