It seems that preaggregate datamap does not support user specified
DMProperties. Howwever it has DMProperties internally.
In the current commit, it will show:
```

|DataMapName|ClassName |Associated Table |DataMap
Properties

'QUERYTYPE'='AGGREGATION', '_internal.deferred.rebuild'='false'|
+-----------+------------+--------------------------------+----------------------------------------------------------------------------------------------------------------------------------------+
```
Do you think it's OK?
