[Chore] Unify interactive queries in tezos-setup

Problem: Some interactive queries use step concept,
while others are done through `yes_or_no`. It's useful
to unify them by using steps only for logging
and for the #568 (non-interactive mode) issue.

Solution: Rewrite delete node data query using steps
instead of `yes_or_no`.
