Hello, I would like to clarify if the following is an expected behaviour.
Connect API returns 500 in the response when creating a connector that already exists or deleting a connector that does not exist. E.g. ``` curl -X DELETE https://localhost:8443/connectors/MirrorSourceConnector { "error_code": 500, "message": "Error trying to forward REST request: Connector MirrorSourceConnector not found" } ``` The API code seem to return 409 for the create call and 404 for the delete call in these cases but the REST client throws new exception with 500 for any response code that is above 400. https://github.com/apache/kafka/blob/trunk/connect/runtime/src/main/java/org/apache/kafka/connect/runtime/rest/RestClient.java#L147 However, when sending a GET request to the API for a connector that does not exist, it returns 404 in the response. It seemed like a bit of an inconsistent behaviour of connect API, so I just wanted to clarify.
