Closes [#31500](https://github.com/fleetdm/fleet/issues/31500)
This change improves `fleetctl` by providing users an alternative to
tabular output. Since MDM command results are often quite large, the
tabular output is usually garbled and hard to read, especially on
smaller screens.
Example new output:
```shell
$ fleetctl get mdm-command-results --id=bfd5fc04-3938-43d1-a280-aa1f53490506 --line
