Enhancement: Support JSON output for diff
Enhancement: Support JSON output and quiet mode for diff
We've added support for getting machine-readable output for snapshot diff, just pass the
flag `--json` for `restic diff` and restic will output a JSON-encoded diff stats and change
list.
Passing the `--quiet` flag to the `diff` command will only print the summary
and suppress the detailed output.
