Add variant type for metadata Add persistent information for variant, including the path of variant sub-columns, persisting them to the segment footer and tablet schema of the rowset.
Now we can not support streamload with column which is map/array nested map/array
serde can do this now , so we can replace it
Notice. if item data in complex type data is empty we just return error, instead of makeup default value , because now we can not define right default for complex type

The root cause of this issue is that Elasticsearch's long type allows inserting floats and strings. Doris did not handle these cases when doing type conversion. The current strategy is to take the integer before the decimal point if a float or string is found.
now we use cast to decimalv3 may has error , because decimalv3 use type precision for translate string
mysql [test]>select cast("9999e-1" as decimal(2,1));
+------------------------------------+
| cast('9999e-1' as DECIMALV3(2, 1)) |
+------------------------------------+
| 999.9 |
+------------------------------------+
1 row in set (0.01 sec)
this pr will fix this just keep reaction same with mysql
mysql> select cast('9999e-1' as decimalv3(2, 1));
+------------------------------------+
| cast('9999e-1' as DECIMALV3(2, 1)) |
+------------------------------------+
| 9.9 |
+------------------------------------+
1 row in set (0.07 sec)
Fix three bugs:
1. Hudi slice maybe has log files only, so `new Path(filePath)` will throw errors.
2. Hive column names are lowercase only, so match column names in ignore-case-mode.
3. Compatible with [Spark Datasource Configs](https://hudi.apache.org/docs/configurations/#Read-Options), so users can add `hoodie.datasource.merge.type=skip_merge` in catalog properties to skip merge logs files.
When a disk io error occurs, errors may occur when reading and writing files in the inverted index. This PR adds error checking to prevent empty files from being generated.

* [improvement](shutdown) not print thread pool error stack trace when shutdown
when thread pool shutdown, should not print error stack trace, it is very confuse.
arrow flight server should not call shutdown, if it is not enabled, because it will print error stack.
remove service unavailable from thrift because it is useless.
Part of this PR need to pick to 2.0 branch.

before the lambda function Expr not implement toSqlImpl() function.
so it's call parent function, which is not suit for lambda function.
