connector_elasticsearch: Test Connection is not compatible with opensearch

[sbidoul]

Module

connector_elasticsearch, when used with opensearch

Describe the bug

When clicking Test Connection and using HTTP basic auth, the following error is reported, even though the parameters are correct and the connector works fine: {"error":"no handler found for uri [/_security/_authenticate] and method [GET]"}.

No urgency to fix, but I report it to save time to other users.
