**Is your feature request related to a problem? Please describe.** With the python feature server, there should be a way to list various objects by type and filter them by tags. **Describe the solution you'd like** Feature server endpoints should be added for listing each of the following object types - - DataSource - Entity - FeatureService - FeatureView - OnDemandFeatureView - StreamFeatureView The user should have the option of filtering by tags and/or bypassing cache where supported. **Describe alternatives you've considered** I considered adding tag filtering to the existing `/get-online-features` endpoint, but this would be insufficient. **Additional context** The feast UI & CLI already allow for filtering by tags. Here's an example of what an addition to `feature_server.py` might look like - ```python from feast.protos.feast.registry.RegistryServer_pb2 import ListFeatureViewsRequest @app.post("/list-feature-views") def list_feature_views(body=Depends(get_body)): try: request = ListFeatureViewsRequest() if body: request = ListFeatureViewsRequest(**json.loads(body)) return store.list_batch_feature_views( tags=request.tags, allow_cache=request.allow_cache ) except Exception as e: # Print the original exception on the server side logger.exception(traceback.format_exc()) # Raise HTTPException to return the error message to the client raise HTTPException(status_code=500, detail=str(e)) ``` with the above endpoint, one could list all feature-views - ```shell curl -X POST "http://localhost:6566/list-feature-views" ``` or filter the list by tag(s) - ```shell curl -X POST \ "http://localhost:6566/list-feature-views" \ -d '{"tags": {"team": "driver_performance"}}' ```
