The goal of this change is to simplify the process of filing
issues with hashicorp/terraform. In the previous Markdown syntax,
the instructions tended to get washed out in a sea of comment
markers. The new Github Form Issues breaks each section into a form
element, with instructions printed clearly as HTML in the page.

We are further hoping to guide users to the correct repository when
filing provider issues, or the community forums when asking usage
questions.
