RewriteBinaryPredicatesRule rewrite expression like
`cast(A decimal) > decimal` to `A > some_other_bigint`
in order to：
1. push down the rewrite predicate
2. avoid convert column A to decimal
We get the datatype of `A` by `expr0.getSrcSlotRef().getColumn().getType()`.
However, when A is result of a function from sub-query, this rule is not applicable.
For example:
```
select *
from (
select TIMESTAMPDIFF(MINUTE,startTime,endTime) AS timediff
from CNC_SliceSate) T
where timediff > 5.0;
```
we cannot push predicate down to OlapScan(CNC_SliceSate) to save effort.
adjust nullable on empty set should apply after unnested sub-query
some function should propagate nullable when args are datev2 or datetimev2

When the argument of truncate function is float type, it can match both truncate(DECIMALV3) and truncate(DOUBLE), if the match is truncate(DECIMALV3), the precision is lost when converting float to DECIMALV3(38, 0).
Here I modify it to match truncate(DOUBLE) for now, maybe we still need to solve the problem of losing precision when converting float to DECIMALV3.
If alter task in queue, compaction is not enabled and may cause too much version.
Keep last 10 version in new tablet so that base tablet's max version will
not be merged and than we can copy data from base tablet to new tablet.
```
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.

* [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.
