Steps to Reproduce - Remote Elasticsearch 7.4

1. Setup a remote Elasticsearch 7.4 with the necessary plugins and cluster name
2. Start DXP
3. Stop the ES6 connector
4. Deploy the ES7 connector
5. Switch to remote mode
6. Reindex

Actual Result: Same as with ES6

Works with the default (embedded) 6.5.0 server
