Print a . while loading

[pmuens]

Corresponding issue: #1446

This PR implements a . printing while loading (e.g. checking if the stack is created).
This will reduce the used terminal real estate dramatically.

The way I was imagining it is that it's just 3 dots maximum and then starts from scratch. Which is much more pretty imo. The way this seems to be setup is that it'll print a . every 5 second, and after 60 seconds (average creation time) you'll end up with 12 dots.

I guess it's not a big deal though. I'm not a big fan of using dots anyway 😛

😆 yes, true. Not the most pretty solution so far but still better than printing the whole message Every time. Maybe we can stick with this for the beginning and improve in the future.

Yup agreed to everything. Much better than the whole output. Can still be improved, but not a big priority imho beyond what we have here. GTM from my side
