`func.sum` may returns `Decimal` that break rest APIs (#15585)
`sqlalchemy.func.sum` has a known *"issue"* that it **may** returns
`Decimal` value (_in my case MySQL 5.7_).
This will cause problem when calling [rest
APIs](https://airflow.apache.org/docs/apache-airflow/stable/stable-rest-api-ref.html#tag/Pool).
E.g.
```http
GET /airflow/api/v1/pools?limit=100
...
TypeError: Object of type 'Decimal' is not JSON serializable
```
