Add issue_template

[sethvargo]

This adds a new issues template modeled after the one we've been using for Vagrant. It mirrors a lot of the information already contained in the CONTRIBUTING.md, but provides a consistent template for new issues to follow as well as some examples.

This text will pre-fill when someone goes to create a new issue.

Maybe also something like: "if the issue appears to affect multiple resources and may be an issue with the core of Terraform, please also mention this".

@jen20 added those things

I kind of like the Homebrew's checklist-style: https://github.com/Homebrew/homebrew-core/blob/master/.github/ISSUE_TEMPLATE.md

I wonder if there's any way we could turn this into a checklist too.

I'm thinking it may feel more natural for people reporting bugs to tick boxes and fill in gaps in the text, instead of removing it and/or answering questions.

e.g.

• I'm running the latest Terraform version (confirmed via terraform -v)
• I'm reporting crash
  • I did attach link to a gist containing crash.log

Hi @radeksimko

The problem I have with Homebrew's template is that those checkboxes only show up after you create the issue, and they aren't versioned or anything. As a result, anyone with permissions can check/uncheck, and when I get an email from GitHub, it might not contain the right "checkboxes". For non-technical users, they might not be familiar with the markdown syntax for [ ] and I don't find the checkboxes helpful to be quite honest.

@sethvargo Thanks for the explanation, these reasons make sense.

Sometimes I see things only from my POV - i.e. someone who knows markdown quite well and almost doesn't see the difference between raw and rendered markdown. 😃

I'm going to lock this issue because it has been closed for 30 days ⏳. This helps our maintainers find and focus on the active issues.

If you have found a problem that seems similar to this, please open a new issue and complete the issue template so we can capture all the details necessary to investigate further.
