adding tainting/untainting as a terraspace command

[AHaymond]

This is a 🙋‍♂️ feature or enhancement.

• [ ] I've added tests (if it's a bug, feature or enhancement)
• [x] I've adjusted the documentation (if it's a feature or enhancement)
• [x] The test suite passes (run bundle exec rspec to verify this)

Summary

Taint and untaint are very useful Terraform commands when you need to force the replacement of a resource. Moving these subcommands as first class citizens for Terraspace reduces overhead in management by no longer requiring a need to shift to the cache directory to drop into the terraform cli to perform such tasks.

This pull request adds them to the Terraspace list of subcommands that can easily be carried out without having to navigate to a cache directory.

One of the few last things I need to "cd" into the cache directory for. Would be great to have this.

Thanks @AHaymond! This will be really nice!

[gradyplayer]

Seems completely reasonable LGTM... (for all that is worth)

[AHaymond]

Any movement on bumping this command to a first class citizen?

[tongueroo]

Been a little busy. Will try to take a look soon. Mainly just needs some testing.

It sure would be nice to have to do less traversal into the cache folder to utilize underlying Terraform commands. A good alternative would be to create a pass through such as terraspace tc [stack] [terraform commands and arguments]
