[JVPP-7] Consider using Streams for dump replies instead of aggregated list in a future

[vvalderrv]

Current APIs return ReplyDump wrappers as reply to dump requests, e.g.:

 

CompletionStage<BridgeDomainDetailsReplyDump> bridgeDomainDump(BridgeDomainDump var1);
 
public final class BridgeDomainDetailsReplyDump implements JVppReplyDump<BridgeDomainDump, BridgeDomainDetails> {
 public List<BridgeDomainDetails> bridgeDomainDetails = new ArrayList();
(...)
}

We could return Stream<BridgeDomainDump> instead.
