feat(api): add ShowResult attribute to plan response

[raulsh]

what

Add new ShowResult attribute in /api/plan endpoint. It reads show output file and put into API response.

why

It allows to use JSON output to create new implementations/tools based on this instead of plain text Terraform output. In my case, I can build a drift detection tools that relies on Atlantis plan execution (instead of executing plan on separate environment).

Even I tried with https://github.com/cresta/atlantis-drift-detection. But just uses Atlantis just to check if a project have changes and locking state if need to do a plan. But after that, it needs to execute a plan outside Atlantis.
