[DO NOT INTEGRATE] ISPN-5036 infinispan-remote tests

[DO NOT INTEGRATE] -- still working on it, need a short review, guide, though. 

Please @tristantarrant, @galderz I know you are busy, once you have a few minutes -- can we go this way here? Raising a need_review asap so I can adapt quickly. 

I am particularly not 100% sure about -- org.infinispan.protostream:sample-domain-implementation deps. 

Thank you for any comments!
