TF 0.12 pretty print google_iam_policy

[marcbas1]

When making a small change to a google project's IAM policy, the terraform plan output becomes completely unreadable. If I remove one user from roles/owner the policy_data shows many more additions and deletions and becomes completely unreadable. We want to make sure from the plan output that it is indeed removing the one user as intended.

For TF 0.12, this is what the output looks like

  # google_project_iam_policy.test-infra will be updated in-place

In TF 0.11 the plan output was something like this:

  # google_project_iam_policy.test-infra will be updated in-place                                                                                                                                                                            
  ~ resource "google_project_iam_policy" "test-infra" {                                                                                                                                                                                      
        etag           = "hdsgJDHGaEC4="                                                                                                                                                                                                       
        id               = "test-infra"                                                                                                                                                                                                        
      ~ policy_data    = { OLD_JSON } -> { NEW_JSON }

We had written a parser for TF 0.11 to parse OLD_JSON and diff against NEW_JSON to help us better identify diffs.

Is it possible to either have TF 0.12 print the json string like TF 0.11 did, or have the diff be more readable in the output.
