Consider removing the support link from the CLI output

[honnibal]

This is definitely a matter of opinion, but I wanted to raise my own reaction and see how others feel.

Personally, I hate the support link that's printed after every error, so much so that I'm thinking of making myself an alias or something that strips it out.

The message is uninformative, especially after the first time it's shown. It also really feels out of place for an open-source tool. As a user I might write a dozen commands in a few minutes that each end with exit 1. So my screen is just full of this message, Having any troubles? Hit us up at https://dvc.org/support, we are always happy to help!, over and over again. This quickly creates quite the opposite feeling from what you're going for.

Anyway, this is definitely subjective, and it intersects with strategic considerations etc. So, up to you! But I thought I'd at least mention my reaction to it.

Hi @honnibal !

Thanks for the feedback! Indeed, printing the footer on every error might be a bit too much. I think we could safely switch to printing it only on unexpected errors. So we would move

dvc/dvc/main.py

Line 94 in 83a2afc

logger.info(FOOTER)

to around

dvc/dvc/main.py

Line 80 in 83a2afc

ret = 255

. What do you think?

I think that sounds like a good step, sure! After all, most of my errors will be things like getting a URL or a path wrong. It doesn't make sense to be told about support in these situations.
