All user visible Durations should be fs.Duration rather than time.Duration. Suffix is then optional and defaults to s. Additional suffices d, w, M and y are supported, in addition to ms, s, m and h - which are the only ones supported by time.Duration. Absolute times can also be specified, and will be interpreted as duration relative to now.
The following command will block for 60s(default) when the network is slow or unavailable:
```
rclone --contimeout 10s --low-level-retries 0 lsd dropbox:
```
This change will make it timeout after the expected 10s.
