Description
Partially fixes hashicorp/terraform-provider-google#8701
This PR changes how the
google_iam_policy
data source stores the user-entered data in its computedpolicy_data
attribute. It is addressing the first issue I describe in this comment on the original issue.I've updated how the
google_iam_policy
data source processes itsbinding
blocks into a JSON string which it stores as thepolicy_data
attribute. I've made this processing resemble what happens in the API, so there should not be a mismatch between the JSON of the policy in the data source's state and the resource's state.Manual tests
