[Enhancement] Add output mode options

[ashleyprimo]

Suggestion: The addition of a --output mode to allow operators to get an alternative output- such as in JSON. Keeping the default without the use of this option as a table.

I recommend the initial additional output be JSON since it's very easily human-readable (if outputted in "pretty" mode) and moreover can be easily imported and parsed in many languages including Python.

Reasoning: I currently manage a very large cluster of FreeIPA servers (over 15 in total), which as I'm sure you can already imagine makes the table a very tricky thing to use unless you let it span a few widescreen monitors.
