> This doesn't actually show any information about the chunks. We can make this command dump the {{BlockData}} retrieved from the {{getBlock}} call with some additional details about the replica, and clean up the json structure.
> The command only works for single key, which is probably fine given that we plan to have fairly verbose output, but the help message needs to be fixed because it says that the URI says that volumes and buckets are also valid, and directory handling is unspecified.
