fix(openlineage): accept custom producer URIs instead of returning 500

[psaikaushik]

Summary

The OpenLineage converter rejects events with custom producer URIs that don't match the hardcoded OpenLineage, Airflow, or Trino patterns, returning a 500 error. According to the OpenLineage spec, the producer field is a URI that can be any value.

Closes #16961

What Changed

OpenLineageToDataHub.java

• Added extractOrchestratorFromProducerUri() helper that extracts the last non-empty path segment from a producer URI to use as the orchestrator name
• In getOrchestrator(), added an else branch for unknown producers that calls the new helper instead of falling through to the RuntimeException
• Existing behavior for OpenLineage, Airflow, and Trino producers is unchanged

OpenLineageOrchestratorTest.java (new)

• 7 tests covering:
  • Custom producer URIs (the bug scenario from the issue)
  • Simple paths, trailing slashes
  • Known producers still work (OpenLineage, Airflow, Trino)
  • processingEngine takes precedence over producer

Before vs After

Before:

POST /openapi/openlineage/api/v1/lineage
{"producer": "https://github.com/myorg/myproducer/blob/v1/client", ...}

=> 500 Internal Server Error (RuntimeException: Unable to determine orchestrator)

After:

POST /openapi/openlineage/api/v1/lineage
{"producer": "https://github.com/myorg/myproducer/blob/v1/client", ...}

=> 200 OK (orchestrator = "client", extracted from last path segment)
