Clean up generics a bit
ISPN-4951 Entry Retriever iterator should rethrow caused exception

* Pass along any local throwable to iterator
* If remote node receives throwable propagate that as a response
ISPN-4982 EntryRetriever doesn't filter and convert activated values
properly
ISPN-4985 MBean Server Builder for JCache TCK moved to main jar

* Removed home-grown CDI bean provider for JCache TCK, instead use
the harness library provided by the spec.
Replace sfl4j-jdk14 dependency with sfl4j-log4j12 so that jboss logging
writes to log4j in the cdi module (and dependents).

Add more debugging around cache listeners. It seems Class.getMethods()
sometimes returns synthetic methods created by overriding a generic method.
