add profile to functional-test to run against wildfly 8

Didn't work. From documentation it seems to be quite different from AS7. https://docs.jboss.org/author/display/WFLY8/Remote+EJB+invocations+via+JNDI+-+EJB+client+API+or+remote-naming+project 
It seems to involve setting up security for all remoting. For now I just don't want to spend the time to customize the standalone.xml further.
