Kusto命令显示引擎类型（V2或V3）
是否有任何 Kusto 命令（不是通过 Azure 门户）来显示引擎版本（V2 或 V3 等）？该命令.show version不提供这条信息。

You can check the default engine version configuration using following command:
.show database <DB-NAME> policy sharding
| project IsEngineV3 = parse_json(Policy).UseShardEngine
If returned value is 'True' - the engine is configured to ingest new data using 'Shard Engine' (aka Kusto Engine v3)
