Improve no interaction mode

[hverlin]

When running ffizer without any interactions (or no tty), ffizer will fail if --update-mode is not set correctly.
I think it should default to keep in this case?

Here is how I would suggest updating the code to cover this use case:
hverlin/ffizer@doc/scripts...hverlin:ffizer:hv/additional-logs

I am also printing the variables values when hidden or --no-interaction is set.

I think probably that checking --no-interaction should be set to true if isatty returns false?
