http-aws-es compatible with new Elasticsearch client.
/* requires AWS creds to be updated.
* if they aren't, update using AWS.config.update() method before instatiing the client.
*
* import this module where you instantiate the client, and simply pass this module as the connection class.
*
* eg:
* const client = new Client({
* node,
* Connection: AwsConnector
* });
