Ported PR fabric8io/fabric8-maven-plugin#1711

+ Add a generator for Open Liberty that extends the java-exec generator. It defaults webPort to the Liberty default port (9080) and adds an environment variable for use by S2I if it detects a Liberty runnable jar.
+ Add Liberty's default web ports (9080, 9443) to the ExposeEnricher so that routes get generated.
