Test logging fix, by default log4j2 looks for log4j2.properties file

[akatona84]

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 #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

@mhratson could u take a look?
originally wanted to fix this along with logback exclusion, but then realized that is already merged, so only file renaming

[mhratson]

@akatona84 can you please include before -> after outputs so i can reproduce myself?

Thanks.

without this pr, just on current main

1. change the logger.kafka.level to degug in file cruise-control-metrics-reporter/src/test/resources/log4j.properties
2. and then run
   ./gradlew :cruise-control-metrics-reporter:test --tests CruiseControlMetricsReporterTest.testReportingMetrics
3. and check the
   cruise-control-metrics-reporter/build/test-results/test/TEST-com.linkedin.kafka.cruisecontrol.metricsreporter.CruiseControlMetricsReporterTest.xml
   file, it only contains error level messages
4. now rename the cruise-control-metrics-reporter/src/test/resources/log4j.properties to cruise-control-metrics-reporter/src/test/resources/log4j2.properties
5. run ./gradlew :cruise-control-metrics-reporter:test --tests CruiseControlMetricsReporterTest.testReportingMetrics again
6. see all kinds of kafka logs in cruise-control-metrics-reporter/build/test-results/test/TEST-com.linkedin.kafka.cruisecontrol.metricsreporter.CruiseControlMetricsReporterTest.xml
