Provides a parent pom that builds runnable war using jetty.
This uses the "maven overlay approach" to put jetty, logging, servlet api and avaje-jetty-runner
into the root path of the war and a manifest entry to point to the RunWar main method. The jars
included in the overlays provide a set of system classes that boot and run the war.
