Immutable. The resource name of the Policy, which must be unique. Format: policies/{attachmentPoint}/denypolicies/{policyId}
The attachment point is identified by its URL-encoded full resource name, which means that the forward-slash character, /, must be written as %2F. For example, policies/cloudresourcemanager.googleapis.com%2Fprojects%2Fmy-project/denypolicies/my-deny-policy.
For organizations and folders, use the numeric ID in the full resource name. For projects, requests can use the alphanumeric or the numeric ID. Responses always contain the numeric ID.
