Refactor `--all_fields` flags

[aarontp]

Right now --all_fields is used to add data to a lot of the turbiniactl status commands, but it is a flag associated with the base turbiniactl instead of status itself, so it's easy to miss. We should copy that, or a separate flag under status to make it more straightforward. The argparse namespace seems to be flat, so we might need to rename this since it is used by other things in turbiniactl.

It might also be a little confusing as to what exactly --all_fields vs. --full_report adds to the status output, so could potentially do some other refactoring to make that more straightforward.
