```
create table tbl1 (k1 varchar(100), k2 string) distributed by hash(k1) buckets 1 properties("replication_num" = "1");
insert into tbl1 values(1, "alice");
select cast(k1 as INT) as id from tbl1 order by id limit 2;
```
The above query could pass `checkEnableTwoPhaseRead` since the order by element is SlotRef but actually it's an function call expr
both update status and open_vectorized_internal will call send_report and stop report thread. move update_status code to open method and remove unnecessary send_report and stop_report_thread.

This pr added support for the pre-aggregation hint. Users could use /*+PREAGGOPEN*/ to enable pre-preaggregation for OLAP table.
For example:
Let's say we have an aggregate-keys table t (k1 int, k2 int, v1 int sum, v2 int sum). Pre-aggregation could be enabled by query with a hint: select k1, v1 from t /*+PREAGGOPEN*/.
Tow improvements:
1. Refactor rowgroup&page filtering in `ParquetReader`, and use the operator overloading of Doris native c++ type to process comparison.
2. Support decimal/decimal v3/date/datev2/datetime/datetimev2
The columns name in stream load and broker load are case sensitive, make it case insensitive. This would be consist with query, because query sql columns name are case insensitve.
* [fuzzy](test) fuzzy some session variables stably according to pull_request_id
* fuzzy enable_fold_constant_by_be

* [regression](fix) 1. fix broker load test case and add orc test 2. set enableBrokerLoad=true in pipeline
* add a load test for the orc file and let it run in the TeamCity pipeline.
--This pr may not pass P0 Regression check since the bug of orc load has not been fixed.--
change the column name in the load sql to lowercase to pass P0 Regression check.
corrected: it's not a bug but a feature.
Show MTMV JOB/Task will list all the jobs and tasks among different databases in spite of the current database.
Now use current db to identify the mtmv tasks and jobs. Only the user who did not use a database can list all job and tasks among different databases.
call pthread condition wait may block brpc thread.
no need wait for fragment because two phase exec fragment already guarantee that the fragment instance exits when runtime filter comes. So that I remove the condition wait code.

Sometimes the profileContent of ProfileElement is very large (more than 30MB), and this kind of huge string object may cause performance problems for gc. But we use them only when we invoke profile relevant restful apis (such as /profile/{format}/{query_id}, /api/profile and so on), so we need to lazy load them.
MetricRegistry::trigger_all_hooks holds the metrics lock and is stuck in get_je_metrics, to_prometheus is waiting for MetricRegistry::trigger_all_hooks to release the lock, so get_je_metrics is no longer called in MetricRegistry::trigger_all_hooks.
Support using this sql to refresh mtmv manually. It can generate a mtmv task right now.
```
REFRESH MATERIALIZED VIEW test_mv_view [complete];
```
You can use `show mtmv task` to show the latest task.
In this pr, I also try to clear the mtmv tasks when drop the mtmv to make sure test suite to be right
