✨ Add progress bar to CLI fetch

[antons-]

This has been needed for a long time, especially with larger Hail organisations with lots of objects.

The current CLI output looks like this. Not nice.

Running Task HailFetchTask

Fetching HailArticleFetching HailImageFetching HailPublicationFetching HailTagFe

We should change it to something like this. Add colors too, why not, and maybe a verbose param so we can see exactly what is being processed.

Running Task HailFetchTask...

Fetching HailArticle...
[====================] 100% (400 of 400)

Fetching HailImage...
[==========__________]  50% (60 of 120)

Whatever is built will need to play nice with cron jobs, more so if the output is emailed once the job is done.

I would suggest you have a look at symfony/console. It makes a lot of those processes like adding progress bars and adding pretty colours to your output a breeze.

Ta, thanks for that @maxime-rainville - I was trying to find this yesterday.

We're thinking about refactoring our own build task around it at some stage. silverstripe/silverstripe-framework#5542

Awesome, I would be very keen for this to happen!
