   ### [INLONG-10721][Sort] Add elasticsearch7 connector on flink 1.18.
   
   
   Fixes #10721
   
   ### Motivation
   
   There is no es connector in sort-connectors， but es is a popular 
distributed, RESTful search and analytics engine.
   
   So, this pr will add the es7 connector onflink 1.18.
   
   ### Modifications
   
   Reference the official connector flink-connector-elasticsearch7 and it will 
support send audit information later.
