[wildfly-dev] MORE_JAVA_OPTS in standalone.sh

This will definitely be an issue. I can guarantee that some will want to 
replace one option that's already defined resulting in a duplicate. 
Processing the either option looking for duplicates is not an option. 
Every time we introduce something that requires scanning JAVA_OPTS it's 
extremely painful and error prone.

In docker wouldn't we just do something like:

RUN echo "JAVA_OPTS=\"$JAVA_OPTS -Dkey.value\"" >> 
$JBOSS_HOME/standalone.conf
