Base module for Hazelcast 3.x and configurable Java kill switch

Added a base module for Hazelcast 3.x and used it for alle 3.x plugins.
Added a configurable Java kill switch (killall or let IDEA live, use sudo or not).
Ignored local-benchmark.xml and provided a sample file instead.
Updated local-settings-example with new options.
I'm not sure about this method. Does it need to tell if it is supporting transactions generally? Or that it currently is running a transactional map?
