Support nerdctl system df command #3942
Description
What is the problem you're trying to solve
It would be great helpful if we can support nerdctl system df command to show the containerd filesystem usage, just like docker system df can show docker filesystem usage.
Describe the solution you'd like
When run nerdctl system df command, it'll show filesystem usage outputs like following:
❯ nerdctl system df
TYPE TOTAL ACTIVE SIZE RECLAIMABLE
Images 17 1 18.25GB 17.26GB (94%)
Containers 3 3 169.2MB 0B (0%)
Local Volumes 4 3 798.66GB 22.62MB (0%)
Build Cache 44 0 0B 0B

To implement this feature, I think we first need to be able to get the SharedSize of an image.
