 Alternative log4j config. Sending data to files in the `logs` directory.

 # Usage

 ```
 $ java -Dlog4j.configurationFile=conf/log4j2.xml -jar target/standalone.jar
 ```

 # Description

 Outputs data to three log files:

 1. app.log: this is the primary log file for the application.
 2. client.log: this is an access.log for client requests.
 3. server.log: this is an access.log for server requests.

 Files will be rotated to an `archive` sub directory based on both
 time and size. Keeps up to 168 files of at most 200MB.
