Use TF-Controller with a plan-only mode

This plan-only mode is designed to be used in conjunction with the Branch Planner. But you can also use it whenever you want to run terraform plan only.

If planOnly is set to true, TF-Controller will skip the apply step, run terraform plan, and save the output.
