FunctionStringConcat::execute_impl resized with size that include string null terminator, which causes ColumnString::chars.size() does not match with ColumnString::offsets.back, this will cause problems for some string functions, e.g. like and regexp.
Test on SSB 100g:
select lo_suppkey, count(distinct lo_linenumber) from lineorder group by lo_suppkey;
exec time: 4.388s
create materialized view:
create materialized view customer_uv as select lo_suppkey, bitmap_union(to_bitmap(lo_linenumber)) from lineorder group by lo_suppkey;
select lo_suppkey, count(distinct lo_linenumber) from lineorder group by lo_suppkey;

test with the patch, exec time: 5.790s
Currently, there are some useless includes in the codebase. We can use a tool named include-what-you-use to optimize these includes. By using a strict include-what-you-use policy, we can get lots of benefits from it.

Follow #17586.
This PR mainly changes:
Remove env/
Remove FileUtils/FilesystemUtils
Some methods are moved to LocalFileSystem
Remove olap/file_cache
Add s3 client cache for s3 file system
In my test, the time of open s3 file can be reduced significantly
Fix cold/hot separation bug for s3 fs.
This is the last PR of #17764.
After this, all IO operation should be in io/fs.
Except for tests in #17586, I also tested some case related to fs io:
clone
concurrency query on local/s3/hdfs
load error log create and clean
disk metrics
* [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

Add `JSON` datatype, following features are implemented by this PR:
1. `CREATE` tables with `JSON` type columns
2. `INSERT` values containing `JSON` type value stored in `String`, which is represented as binary format(AKA `JSONB`) at BE
3. `SELECT` JSON columns
Detail design refers [DSIP-016: Support JSON type](https://cwiki.apache.org/confluence/display/DORIS/DSIP-016%3A+Support+JSON+type)
* add JSONB data storage format type
* fix JsonLiteral resolve bug
* add DataTypeJson case in data_type_factory
* add JSON syntax check in FE
* add operators for jsonb_document, currently not support comparison between any JSON type value
* add ColumnJson and DataTypeJson
* add JsonField to store JsonValue
* add JsonValue to convert String JSON to BINARY JSON and JsonLiteral case for vliteral
* add push_json for MysqlResultWriter
* JSON column need no zone_map_index
* Revert "JSON column need no zone_map_index"
This reverts commit f71d1ce1ded9dbae44a5d58abcec338816b70d79.
* add JSON writer and reader, ignore zone-map for JSON column
* add json_to_string for DataTypeJson
* add olap_data_convertor for JSON type
* add some enum
* add OLAP_FIELD_TYPE_JSON type, FieldTypeTraits for it and corresponding cases or functions
* fix column_json offsets overflow bug, format code
* remove useless TODOs, add CmpType cases for JSON type
* add license header
* format license
* format be codes
* resolve rebase master conflicts
* fix bugs for CREATE and meta related code
* refactor JsonValue constructors, add fe JSON cases and fix some bugs, reformat codes
* modification be codes along code review advice
* fix rebase conflicts with master
* add unit test for json_value and column_json
* fix rebase error
* rename json to jsonb
* fix some data convert bugs, set Mysql type to JSON
We already separate Array Offset64 and String Offset(32bit) in PR: #12341
Now we limit: Offset inside IColumn, Offset64 only inside ColumnArray, to avoid abuse of them.
If we use the wrong one, it will compile failed.
In old Doris version string offsets are 32bit, but it is not enough for Array type.
If we change string offsets from 32bit to 64bit, there will be problem if we upgrade BE one by one. Because at the same time 32bit Offsets and 64 bit Offsets String will exist at the same time.
As a result, we separate the Codes for Array Offsets.

When the length of `Tuple/Block data` is greater than 2G, serialize the protoBuf request and embed the
`Tuple/Block data` into the controller attachment and transmit it through http brpc.
This is to avoid errors when the length of the protoBuf request exceeds 2G:
`Bad request, error_text=[E1003]Fail to compress request`.
In #7164, `Tuple/Block data` was put into attachment and sent via default `baidu_std brpc`,
but when the attachment exceeds 2G, it will be truncated. There is no 2G limit for sending via `http brpc`.
Also, in #7921, consider putting `Tuple/Block data` into attachment transport by default, as this theoretically
reduces one serialization and improves performance. However, the test found that the performance did not improve,
but the memory peak increased due to the addition of a memory copy.
SQL with JOIN and columns ARRAY, will call function ColumnArray::replicate. At this pr,
we implement replicate for ARRAY type, to support SQL like this:
`SELECT count(lo_array),count(d_array),SUM(lo_extendedprice*lo_discount) AS REVENUE FROM lineorder, date WHERE lo_orderdate = d_datekey AND d_year = 1993 AND lo_discount BETWEEN 1 AND 3 AND lo_quantity < 25;`
1. solved the previous delayed unit test file size is too large (1.7G+) and the unit test link time is too long problem problems
2. Unify all unit tests into one file to significantly reduce unit test execution time to less than 3 mins
3. temporarily disable stream_load_test.cpp, metrics_action_test.cpp, load_channel_mgr_test.cpp because it will re-implement part of the code and affect other tests
