WFLY-2419, WFLY-2363 SFSBs should be distributable by default in HA profiles, deprecate @Clustered

https://issues.jboss.org/browse/WFLY-2419
https://issues.jboss.org/browse/WFLY-2363

Just as before, clustering/passivation can be disabled per bean via @Stateful(passivationCapable=false) or via specifying an alternative cache via @Cache.
Deployment topology will also be dynamic by default in HA profiles, but, just as before, it is up to the EJB client to either make use of it or not.
