log4j.properties being included in fat jar, not log4j2.properties

Overview

While running the module locally using the fat jar, I noticed that there wasn't any output from the logger... Upon investigation I found that:

src/main/resources/log4j.properties still exists and is being copied into the fat jar.
the log4j2.properties file lives under src/test/resources and is NOT being copied into the fat jar.

There are also a few places in the pom which expilcitly point to the old log4j.properties.

This should be cleaned up.

• remove the old log4j.properties
• copy/move the log4j2.properties from src/test/resources to src/main/resources so it's included in the fat jar.
• set the log4j2.configurationFile system property instead of log4j.configurationFile in the surefire plugin configuration in pom.xml

Acceptance Criteria

• log4j2 is used by unit tests
• log4j2.properties is included in the fat jar
• references to log4j.properties are cleaned up.
