The test is a stress test which queries all system tables in parallel.
System table SYSTEM.MODELS is now populated using the library-bridge.
This made the test fail with error:
2022-09-12 23:51:34 Code: 410. DB::Exception: Received from localhost:9000. DB::Exception: BridgeHelper: clickhouse-library-bridge is not responding. (EXTERNAL_SERVER_IS_NOT_RESPONDING)
2022-09-12 23:51:34 (query: SELECT * FROM system.models LIMIT 10000 FORMAT Null)
Looking at the logs, the server tried to start the library-bridge when
querying SYSTEM.MODELS but multiple handshake attempts failed.
So (most likely) the infrastructure is slow or (unlikely) there are
settings in CI (e.g. a firewall) preventing communication with the
bridge. Because 1. other system tables are also excluded (zookeeper,
merge_tree_metadata_cache), 2. SYSTEM.MODELS is tested in integration
test "test_catboost_evaluate" and 3. the test runs locally just fine, I
am excluding SYSTEM.MODELS from it.
