Use correct JAXB artifacts

I was looking through my dependencies, as I was upgrading to the new JAXB version (2.3.1) and I noticed a few legacy-looking dependencies pulling in an older version (2.3.0, but thats another issue). To me it seems, that optaplanner-persistence-jaxb pulls in wrong JAXB artifacts with wrong scope.

According to the JAXB developers, the artifact names have changed .

My local testing suggests, that the JAXB dependencies of optaplanner-persistence-jaxb can be heavily streamlined, as my local testing with

$ mvn test -Denforcer.fail=false

succeeded.

I removed:

• org.jboss.spec.javax.xml.bind:jboss-jaxb-api_2.2_spec
• com.sun.xml.bind:jaxb-core
• com.sun.xml.bind:jaxb-impl
• javax.activation:activation

And added:

• javax.xml.bind:jaxb-api:2.3.1
• org.glassfish.jaxb:jaxb-runtime:2.3.1 (in test scope)

I don't know, which artifacts are being pulled in by other JBoss projects, as I only use optaplanner-persistence-jaxb with dependencies in that regard.
