Migrate commans Cleo command-line

[estyxx]

Refactoring/improve the commands using Cleo like poetry does see commands.

I think Cleo is a nice tool to write command line commands like poetry, and it enables to write tests! I think we could think to migrate to it in order to clean up some scripts and start to write some tests :)

What do you think @justinmayer?

I like the idea.

I wonder if we can write some tests now so that when we start refactoring for Cleo we have some sanity checks, what do you think?

[estyxx]

Yeah, I can start prototype some refactoring and see if can be an improvement :)
Otherwise, until now I always test locally...
