Description

What problem are you are trying to solve?

I want rclone to have the same support for file permissions/etc that rsync provides with SFTP.

How do you think rclone should be changed to solve that?

I believe the implementation is as simple as turning on metadata support for SFTP for mode, uid, gid, atime, mtime.

Research direction
Investigate the SFTP backend implementation in rclone (e.g., backend/sftp/). Look at how metadata is handled for other backends (e.g., local, s3). Check if the SFTP library used (likely github.com/pkg/sftp) supports these attributes. Implement reading/writing of mode, uid, gid, atime, mtime in the SFTP backend's List and Put operations. Test with various SFTP servers.
