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.
for some reasons, transaction pushlish succeed replica num less than quorum,
this transaction's status can not to be VISIBLE, and this publish task of this
replica of this tablet on this backend need retry publish success to
make transaction VISIBLE when last publish failed.

In the past, only simple predicates (slot=const), and, like, or (only bitmap index) could be pushed down to the storage layer. scan process:
Read part of the column first, and calculate the row ids with a simple push-down predicate.
Use row ids to read the remaining columns and pass them to the scanner, and the scanner filters the remaining predicates.
This pr will also push-down the remaining predicates (functions, nested predicates...) in the scanner to the storage layer for filtering. scan process:
Read part of the column first, and use the push-down simple predicate to calculate the row ids, (same as above)
Use row ids to read the columns needed for the remaining predicates, and use the pushed-down remaining predicates to reduce the number of row ids again.
Use row ids to read the remaining columns and pass them to the scanner.
Notice some changes:
1. Support cancel query for mysql load
2. Change the thread pool for mysql load manager.
3. Fix sucret path check logic
4. Fix some doc error
before this pr, add or drop inverted index not change table state, maybe multiple alter jobs executed at the same time, that may lead to some unexpected problems.
refactor cost-model frameWork:
1. Use Cost class to encapsulate double cost
2. Use the `addChildCost` function to calculate the cost with children rather than add directly
Note we use the `Cost` class because we hope to customize the operator of adding a child host. Therefore, only when the cost would add the child Cost or be added by the parent we use `Cost`. Otherwise, we use double such as `upperbound`
1. 'insert into' profile has 'insert' type, can not query by 'load' type
2. 'insert into' profile does not have job_id, can not query by job_id. so put all profiles key with query_id
3. 'broker load' profile does not have some infos, npe
ECB algorithm, block_encryption_mode does not take effect, it only takes effect when init vector is provided.
Solved: 192/256 supports calculation without init vector
For other algorithms, an error should be reported when there is no init vector
Initialization Vector. The default value for the block_encryption_mode system variable is aes-128-ecb, or ECB mode, which does not require an initialization vector. The alternative permitted block encryption modes CBC, CFB1, CFB8, CFB128, and OFB all require an initialization vector.

Note: This fix does not support smooth upgrades. during upgrade process, query may report error: funciton not found
* A in(B) -> bitmap_contains(bitmap_union(B), A)
support bitmap runtime filter on nereids
* GroupPlan -> Plan
* fmt
* fix target cast problem
remove test code

In the past, pg catalog use sql SELECT schema_name FROM information_schema.schemata where schema_owner='<UserName>'; to select schemas of an user. Howerver, this sql can not find all schemas that a user can access, that because:
A user may not be the owner of an schema, but may have read permission on the schema.
A user may inherit the permissions of its user group and thus have read permissions on one schema.
For these reasons, we replace the sql statement with select nspname from pg_namespace where has_schema_privilege('<UserName>', nspname, 'USAGE');
