migrate user feedback to use display module

[edublancas]

we might still have some print statements to display user feedback, we should migrate them to use the new display module: #432

[anupam-tiwari]

For this one, should I replace all print statements with display module?

[edublancas]

yes, all print statements which are meant to the end-user should be replaced (I think it's all of them but open an PR and I can provide feedback in case there are any exceptions)

[edublancas]

any progress here? @anupam-tiwari

[anupam-tiwari]

working on it!
