and configurale cascadin
When initializing a Snowflake hook or operator, the value used for
`snowflake_conn_id` was always `snowflake_conn_id`, regardless of whether or
not you specified a value for it. The default `snowflake_conn_id` value is now
switched to `snowflake_default` for consistency and will be properly overriden
when specified.
+### Simplify the response payload of endpoints /dag_stats and /task_stats
+
+The response of endpoints `/dag_stats` and `/task_stats` help UI fetch brief
statistics about DAGs and Tasks. The format was like
+
+```json
+{
+ "example_http_operator": [
+ {
+ "state": "success",
+ "count": 0,
+ "dag_id": "example_http_operator",
+ "color": "green"
+ },
+ {
+ "state": "running",
+ "count": 0,
+ "dag_id": "example_http_operator",
+ "color": "lime"
+ },
+ ...
+],
+...
+}
+```
+
+The `dag_id` was repeated in the payload, which makes the response payload
unnecessarily bigger.
+
+Now the `dag_id` will not appear repeated in the payload, and the response
format is like
+
+```json
+{
+ "example_http_operator": [
+ {
+ "state": "success",
+ "count": 0,
+ "color": "green"
+ },
+ {
+ "state": "running",
+ "count": 0,
+ "color": "lime"
+ },
+ ...
+],
+...
+}
+```
