71807ceb5f [Enhancement](tvf) Table value function support reading local file (#17404)
I tested the local tvf with tpch queries. First, generate `lineitem` datasets with 6001215 rows, and load it into `lineitem` table by:
```
insert into lineitem select c11, c1, c4, c2, c3, c5, c6, c7, c8, c9, c10, c12, c13, c14, c15, c16 
from local(
        "file_path" = "tools/tpch-tools/bin/tpch-data/lineitem.tbl.1", 
        "backend_id" = "10003", 
        "format" = "csv", 
        "column_separator" = "|"
);
```
Then, run `q1` and `q16` tpch queries, the query result is correct.

It can also analyze the BE's log directly like:

```
mysql> select * from local(
        "file_path" = "log/be.out",
        "backend_id" = "10006",
        "format" = "csv")
       where c1 like "%start_time%" limit 10;

e412dd12e8 [chore](build) Use include-what-you-use to optimize includes (PART II) (#18761)
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.

05db6e9b55 [refactor](file-system)(step-2) remove env, file_utils and filesystem_utils (#18009)
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
