Implement non-interactive/partial interactive mode for tezos-setup-wizard

[itkach]

Clarification and motivation

It would facilitate scripting and copy-paste distribution of setup instructions if tezos-setup-wizard had a non-interactive mode

Acceptance criteria

• Non interactive mode: take user input from the command line, fail with a instructive error message in case of errors or incomplete input
• Partial interactive mode: take user input from the command line, drop into interactive mode on errors or in case of incomplete input (skipping wizard steps where input was given on the command line)
