client.ContainerDiff already validates the given container name/ID, and
produces an error when empty, so we don't have to check for this;
https://github.com/moby/moby/blob/abba330bbfe10765822b59bb68af99db439736ba/client/container_diff.go#L13-L16
While updating, also;
- remove the diffOptions type, as there were no other options, and make
the container name/ID a string argument.
- fix camelCase nameing of dockerCLI
Before this patch:
docker diff ""
Container name cannot be empty
With this patch:
docker diff ""
invalid container name or ID: value is empty
