This config means the bot will look at issues with more information required label on it and if it's been inactive for 7 days it will close it with the comment listed here.

Is the VS Code bot from Microsoft available? I recall that one being smarter in not just closing things with more-information-required but also anything that just didn't have any reasonable activity.

I thought we removed Travis completely. How come we still have a .travis.yml?

[lcampos]

Not sure but I can remove it as part of this PR.

They use several bots but based on their config I think they might have their own bots. The closest one I found was this and another one called Stale (https://probot.github.io/apps/stale/). Stale looks at both issues & PRs and closes them based on certain configurable params. I thought it was a bit too much based on how many open issues we have that are waiting on further info from the author.

OK. Let's go with this one first and see if we need to change. I don't have any better recommendations and we can always switch later.
