Mingyu Chen 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
