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
