Way to turn off cargo progressbar

[mocsy]

Since 1.30 Cargo comes with a strange progress-bar which is turned on by default.
It significantly increases the lines on the output and requires a lot more scrolling if I want to look at what cargo did.
I want to turn it off permanently.

Maybe off by default would be nice for anything large enough to have more than 3 dependencies?

Example output from my console:

Building [====================================================> ] 212/216: Building [====================================================> ] 212/216: Building [====================================================> ] 212/216: Building [=====================================================> ] 213/216: Building [=====================================================> ] 213/216: Building [=====================================================> ] 213/216: Building [=====================================================> ] 214/216: Building [=====================================================> ] 214/216: Building [=====================================================> ] 214/216: Building [=====================================================> ] 214/216: Building [=====================================================> ] 214/216: Building [=====================================================> ] 215/216: Finished dev [unoptimized + debuginfo] target(s) in 1m 32s

Nothing useful here to see, got to scroll back an entire screen to find a useful information.

@Eh2406 I'm not so sure, because using +beta the progress-bar disappears correctly and doesn't spam the output window.

I think it's fixed already, because it works fine for me with +beta.
