Changes

Pom fixes (#4013)
* add provided scope back on jaxb-api
* make the jersey-bom NOT inherit the jersey parent pom, it adds non
desired dependency management
* make hk2-config optional to cut it from the exposed dependencies
* add version in bom/pom.xml explicitly to not use the one from the
parent
