Adding flag to toggle wrapped default

[mhumeSF]

Heavy user of Atlantis and ran into a situation where users over-looked the changes of a plan because it had been wrapped. Thought adding a toggle for this behavior would be helpful for those who wanted to opt-out

[mhumeSF]

Looks like I'll need to add an updated test to cover the scenario of when the flag is used.

If you run plan a lot on a pull request though the output gets huge. Are you sure you're going to want to set this globally?

[mhumeSF]

It would be better if this could be set per repo. Where would I look at setting per repo attributes?

[mhumeSF]

I could see the use case where one might want either behavior. To enable globally or per repo. This should be ok to add as well as per repo.

[mhumeSF]

Was able to get this working at the repo level. Adding wrapped: false in atlantis.yaml will toggle wrapped, though pretty certain there is a better way to do this.

[lkysow]

Sorry but I've changed my mind! Let's just add the cli flag for now and see if folks ask for per-repo control.

Let's also change the flag to --fold-long-output.

Sure thing, I'll update.

@lkysow I was getting tripped up on testing with flags thinking I had to provide a parameter to bool flags i.e. --fold-long-output false, but this is not the case. I've updated the flag to --disable-folding-long-output because this feels more obvious in what is happening.

@lkysow This look good?

[lkysow]

Merged in #960. Thanks so much!
