In BE, There is an implicit convention that HashJoinNode's left child's output Slot must before right child's output slot in intermediateTuple.
However, after we do commute rule on join plan in Nereids, this convention will be broken and cause core dump in BE.
There are two way to fix this problem:
1. add a project on join after we do commute
2. reorder output of join node when we do translate
Since we cannot translate project yet because BE projection support is on going(#11842). So we use second way to fix it now. After the project translation could work correctly, we should use the first way to fix it.
In current implementation, we detect invalid slot at execute phase. At execute phase, it is hard to get useful information for further debug. This pr moves error detection ahead to prepare phase, so that we can log related tuple descriptors.
Refactor TaggableLogger
Refactor status handling in agent task:
Unify log format in TaskWorkerPool
Pass Status to the top caller, and replace some OLAPInternalError with more detailed error message Status
Premature return with the opposite condition to reduce indention
Problem:
1. `enable_array_type` is masterOnly;
2. dynamic open config only affect FE MASTER
`admin set frontend config("enable_array_type"="true");`
3. query in FE FOLLOWER will fail, because of `enable_array_type` is false in FE FOLLOWER
`select * from table_with_array `
Solution:
Only check `enable_array_type` while creating new tables with array column.

1. Rewrite Filter(Project) to Project(Filter) to make sure when do partition prune the tree looks like this: Project(Filter(OlapScan)).
2. Enable the MergeConsecutiveProject MergeConsecutiveFilter rules.
3. prune range partition just like what Legacy Planner do.
Parse parquet data with dictionary encoding.
Using the PLAIN_DICTIONARY enum value is deprecated in the Parquet 2.0 specification.
Prefer using RLE_DICTIONARY in a data page and PLAIN in a dictionary page for Parquet 2.0+ files.

This PR fix three problem in Nereids.
- Add selected index, partition and tablet Info in LogicalOlapScan
- with JoinReorderContext in new LogicalJoin
- fix compute data size when no column size info in StatsCaculator
Return the real process memory information when the process exceeds mem limit
Optimize the memory exceed limit log printing logic
process tracker does not participate in process memory limit.
* table function node enhancement
* also avoid copy for non-vec table function node
* fix table function node output slots calculation while lateral view involves subquery
