update broadcast join cost estimate according to BE implementation.
there is an enhancement on BE. in broadcast join, BE only build one hash table, not instanceNum hash tables.
1. Support for more expression type
2. Support derive with histogram
3. Use StatisticRange to abstract to logic
4. Use Statistics rather than StatisDeriveResult
After adding a unique ID, the unRankTest fail because each plan has a different ID in the string.
To avoid the effect of unique ID, Compare the plan with the output rather than the string
* [Feature](vectorized)(quantile_state): support vectorized quantile state functions
1. now quantile column only support not nullable
2. add up some regression test cases
3. set default enable_quantile_state_type = true

Read IO would be a problem when reading inverted index from disk.
Using read buffer to reduce IO.
Set use buffer flag to be true when reading internal bytes in compound reader for inverted index.
1. introduce a new type `VARIANT` to encapsulate dynamic generated columns for hidding the detail of types and names of newly generated columns
2. introduce a new expression `SchemaChangeExpr` for doing schema change for extensibility
This pull request for bellow problem :
regression pipleline fail case always meet error "Failed to create partition. Timeout. Unfinished mark: 10003=57059", so adjust tablet_create_timeout_second to 100
WITH t0 AS(
SELECT report.date1 AS date2 FROM(
SELECT DATE_FORMAT(date, '%Y%m%d') AS date1 FROM cir_1756_t1
) report GROUP BY report.date1
),
t3 AS(
SELECT date_format(date, '%Y%m%d') AS date3
FROM cir_1756_t2
)
SELECT row_number() OVER(ORDER BY date2)
FROM(
SELECT t0.date2 FROM t0 LEFT JOIN t3 ON t0.date2 = t3.date3
) tx;
The DATE_FORMAT(date, '%Y%m%d') was calculated in GROUP BY node, which is wrong. This expr should be calculated inside the subquery.
Some HDP/CDH Hive versions use gzip to compress the message body of hms NotificationEvent,
so com.qihoo.finance.hms.event.MetastoreEventFactory can not transfer it rightly.
1.if be is dead and be ip not changed by FQDNManager，A situation may occur that after a while the old ip is used by other new alive pod，this may cause two be share same ip which is unexpected.
2.when enable_fqdn is false, user can still set hostname in be when add backend

This is PR introduce splitter interface external table.
The splitter interface contain one method getSplits, which is used by QueryScanProvider to get the external file split.
For Hive/Iceberg/TVF, a split is a file block. For ES, it is a shard.
This PR also move the getSplits logic in FileScanProviderIf to the new Splitter interface.
In the future, we may unify internal table as well.
Support delta encoding and rle(bool) to read Glue data
add delta bit pack decoder,
add delta length byte array decoder,
add delta byte array decoder.
add rle bool decoder.
We find some data type is read with delta encoding on AWS Glue, so it should be supported.
The definition of delta encoding can refer to the delta encoding in parquet.
