VFS caching can now be configured per-remote. Disabling it is equivalent to `rclone mount --vfs-cache-mode none`. This will disable support for random writes and prevent failed uploads from being retried. However, it allows uploads to begin immediately and allows the client to show more accurate file write progress. If a remote type does not support streaming, VFS caching will be force enabled and the UI option will be grayed out. This is preferable to allowing the user to set a broken configuration and not knowing until they try to create a file and having it fail. Internally, RSAF now maintains two sets of VFS instances. One set with caching VFSs and another set with streaming VFSs. This allows the caching option to be toggled immediately without waiting for open files to be closed (and fully uploaded). The downside is that if the user toggles the option while uploads are occurring, the directory listings may be inconsistent until the uploads complete.
