vertxHttpReqInfo only supports GET (Unable to call HTTP POST or PUT etc)

Hi There,

I'm able to consume the Kafka Message, but while i trigger the async API call using

```
Stream> resultStream = parallelConsumer.vertxHttpReqInfoStream(record -> {
String apiReq = "{id:1}";
// Need to call POST VERB
Map params = UniMaps.of("recordKey", "12345", "payload", apiReq );
return new VertxParallelEoSStreamProcessor.RequestInfo("abc.workin.net", 8443, "/api/v1/limit", params);
```

This is internally calling `GET` VERB ( not `POST` VERB ). Can someone help me understand the `POST` call ?

Start at the vertxHttpReqInfoStream entry point and the RequestInfo construction shown in the issue, then trace how its params are turned into an HTTP request. Check the issue discussion for the intended POST behavior and any existing HTTP request tests. Done means the API can issue the requested POST, with the expected request data, without regressing the current GET path.
