Show loading-indicator while Project is uploading

[TonySpegel]

Pretty much the title,

I was wondering if my CLI was frozen or something but nope, it just may take a while to upload everything. And for this case it'd be neat to have a loading-indicator of some kind.
Otherwise it's just ES5 bundle generation complete. and then after quite some time:
🚀 Successfully published via angular-cli-ghpages! Have a nice day!
Somewhere in between these two would be nice :)

And thank you for your great work

Thanks for the suggestion! If we do so, it should have an opt-out via a "progress=false" or "no-progress" flag. Otherwise it would pollute CI logs.

That's a nice idea. It would be difficulty to figure out the real progress, because the upload is done via git executable and we would need to grab somehow the output from there.

@TonySpegel Is it fine for you too if it just prints: Uploading via git, please wait... ?!
@fmalcher Logs are already polluted because of the progress of the build. Our circle logs are very long because of that... 🙄

[fmalcher]

@JohannesHoppe There should be a --no-progress option in angular-cli-ghpages that forwards to the build process!

[TonySpegel]

@JohannesHoppe of course, that would be sufficient =)

I added the text:

👨‍🚀 Uploading via git, please wait...
