Update profiles for Wildfly

Taking a closer look at how test structure looks like, I saw that running tests against Wildfly:
mvn clean verify -Pwildfly-managed
will launch Arquillian profile named jbossas-managed-7.
Similar situation is with remote profile (and maybe other tiny bits).

This naming seems inappropriate and highly confusing when (for instance) you need to temper with Arq. settings in order to debug code.

I would suggest adding separate profiles to arquillian-jboss.xml.

Apart from this, what do you think about updating the default WFLY from 8 to 9 (or even 10, there is CR4 already)?

Will send a PR with these tiny changes soon.
