Terraform Azure Changes

This action will run a terraform plan and output the changes to be digestable and added to a pull request comment. The current states supports azuread_group integration, and will lookup what groups were added, removed, or changed, as well as what users were added, removed, or changed from the provided azuread groups.

Inputs

It is recommended you use this action along with the azure/login action, as it requires you to set the ARM environment variables: (ARM_CLIENT_ID, ARM_TENANT_ID, ARM_CLIENT_SECRET). If you do not provide these variables, you will need to provide them as inputs to this action.

Note: The only required input is group_names. All other inputs are optional and will be pulled from the environment variables if not provided as long as you have the ARM environment variables set.
