Terraform-plan-Action

Terraform is a popular infrastructure as code tool which help us to store our infrastructue as human-readable configuration files that we can version, reuse, and share.This action will perform basic terraform plan operation and return the code changes will bring any infrastructure changes or not.

The main objective of the action is not limited to just terraform plan operation, as we know terraform is a powerfull tool,let me give an example if someone added the code for a static website to github at that time we can host a static site in AWS with the help of terraform,so we can modify this action based on our constraints,also this action originated from the thought of versioning terraform configurations.
