Shift away from term crate

[kinnison]

The term crate is unmaintained. cf. Stebalien/term#93

It is recommended we shift to termcolor (https://crates.io/crates/termcolor)

Whatever the move is toward, it ought to be away from an unmaintained and troublesome crate.

Doing this may solve #1800

I'd like to take this. :)

[kinnison]

@jens1o Cool, thank you, if you want to discuss things, you should come onto the Rustup discord on https://discord.gg/cKdYFVz and we can talk.

I like this.

[pickfire]

I believe this is solved?

[kinnison]

I believe this is solved?

@pickfire At this time we're still using term because we had issues with other options

[Rudi3]

I'm not sure what exactly you need, but what about https://github.com/crossterm-rs/crossterm?

[kinnison]

That looks potentially good, though I was thinking more about a crate which integrates progress bars and messages.

[Rudi3]

I see, what about https://github.com/mitsuhiko/indicatif then?

[kinnison]

Yeah something like Indicatif would be good. It'll be quite a bit of work to rearrange all the output to go properly via that, but it would potentially allow some cleanup.

What was the issue with termcolor? Isn't that what cargo uses?

[kinnison]

I don't recall what prevented termcolor from being suitable, likely something to do with how we currently (hackily) do progress bars.
