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:

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.
