Add support for Hazelcast 4

You can now use Hazelcast 4 with our JTA/XA transactions, via an additional module "transactions-hazelcast4". This was required due to breaking API changes that were introduced in Hazelcast 4.

Technical details

When using the prior Hazelcast integration (made for Hazelcast 3, not 4) you would get the following exception when trying to configure a JTA/XA enabled HazelcastInstance:

java.lang.UnsupportedOperationException: Client config object only supports adding new data structure configurations

Changes impacting client API

If you are using the recommended configuration method then nothing changes, although we did simplify the event com.atomikos.hazelcast4.HazelcastDetectedEvent to contain only the uniqueResourceName. The rest of the information (i.e., password and XML configuration information) has been removed from the event.
