Add ability to dump summary as comment

[logicminds]

When a larger plan is shown in bitbucket it becomes near impossible to see the summary of events as they get shuffled around in many large and long comments. This has caused us to review with less confidence because we can't see the overall summary without a 5 minute search.

To combat this I need to dump the summary using tf-summarize as a comment after atlantis runs the plan. I would like atlantis to incorporate the tf-summarize tool and post it as a top level comment above the plan without resorting to post plan configurations.

Idea: Have option to include summary with a few configurable parameters that uses tf-summarize tool. Dump that output to the top of the PR. https://github.com/dineshba/tf-summarize

I build a custom image anyway, since I use terragrunt and need to bake that and other shit into the container. I started playing with tf-summarize in atlantis today and for the life of me I cannot get it to work. I can run it by itself just fine, even within the container. But when it is triggered in my custom workflow as a run statement, it hangs. The process just sits there. Anyone get this working?
