JAMES-3724 - Enable leak detection mode is testing for test suite

[vttranlina]

Jira: https://issues.apache.org/jira/browse/JAMES-3724

[vttranlina]

WIP
This is my idea regarding the way to do it.
Create jvm.properties in classpath resources, declare testing mode. When creating the server, invoke org.apache.james.ExtraProperties#initialize for setting system properties.

Please apply https://maven.apache.org/surefire/maven-surefire-plugin/examples/system-properties.html to do it everywhere without code changes
