Add dry-run,no-color,with-breakpoints,continue-on-error functionality

[karampok]

As part of me using the library for demos, I had to modify the library code to add the following functions

--dry-run                     run the demo and only prints the commands (default: true)
--no-color                    run the demo and output to be without colors (default: false)
--with-breakpoints            breakpoint (default: false)
--continue-on-error           continue if there a step fails (default: false)

This is a fully draft PR. In case you want, I can work towards improving the code for merging. Thanks

@karampok do you mind a rebase?

[karampok]

Is there anything more from my side?

We may wanna update the README.md documentation, though.
