-------------------------------------

Hi, [~tzulitai] I guess you should be more familiar with this module. Could you take a look on this ? I found  {{createClient}} in {{Elasticsearch2ApiCallBridge}} is hardcoded by a {{TransportClient}}, and it is based on the TCP transport protocol. It is also appear in {{Elasticsearch5ApiCallBridge}}. I have some idea in my mind, either rename {{Elasticsearch2ApiCallBridge}} to {{Elasticsearch2ApiCallBridgeByTcp}} or something like that, or create a new class that implement {{ElasticsearchApiCallBridge}} interface for supporting create a client based on JestClient. What do you think of them ? It would be great if you can improve my mind.

> Currently, all connectors as far as I have known that merely support the TCP transport protocol of Elasticsearch, but some of company's ES cluster just relies on the HTTP protocol, and close the TCP port on production environment. So, I suggest add a new implemention for creating a HTTP protocol by using {{JestClient}}, which is a Java HTTP Rest client for ElasticSearch.
