Atlantis: Formatting is broken when comments are continued on GitHub

[timoguin]

When long Terraform plan output gets split into multiple comments on GitHub, the Markdown formatting is unrendered in the subsequent comments.

Here's a screenshot with some example output:

It seems this is due to splitting the comment _after_ the Markdown has been rendered. I'm guessing the second comment needs the triple backticks (```) that get stripped out.

Markdown rendering and comment creation are done here:

Splitting is done here:

Yes my initial solution was a bit hacky. This needs to be cleaned up.

Looks like this needs to take into account https://github.com/runatlantis/atlantis/issues/251. For long outputs spread across 2 comments, I have seen that the first output renders okay and is in a collapsed block (as implemented in https://github.com/runatlantis/atlantis/issues/251), but the second comment is not formatted nicely, as in this issue.

I'm seeing the same behavior as @julianvmodesto

If anyone has bandwidth to take a look that would be great. https://github.com/runatlantis/atlantis/pull/203 was started but never finished.

Simply removing the Refreshing.... lines might be a quick-win and move lots of plans under the character limit.
