Pull processing for WildFly and WildFly core was just moved to JDK 8.
This was done as part of effort allow testing also java 8 features as part
adds "java8" integration
This module uses java 8 as source & target where all tests utilizing java8
features should be added.
WildFly source level is still at 7 with exception of this new module ^^
Master & Master-ignore jobs on brontes will still use JDK7 for running
to make sure no JDK8 APIs slip into code base by mistake.
