Description

Data Fusion recently added support for encrypting instance metadata with Customer Managed Encryption Keys (CMEK). This is a key requirement for regulated industries and key customers. The Terraform module should also support this configuration so that customers to prefer automated deployment can take advantage of CMEK with CDF.

Potential Terraform Configuration

# Propose what you think the configuration to take advantage of this feature should look like.
# We may not use it verbatim, but it's helpful in understanding your intent.
resource "google_data_fusion_instance" "instance" {
  provider                      = google-beta
  name                          = "datafusion"
  description                   = "datafusion instance"
  region                        = "europe-west-2"
  type                          = "developer"
  enable_stackdriver_logging    = false
  enable_stackdriver_monitoring = false
  cmek_key                = "projects/PROJECT_ID/locations/REGION/keyRings/KEY_RING_NAME/cryptoKeys/KEY_NAME"
  private_instance              = false
  version                       = "6.45.1"
}

Note: This feature is only available in Data Fusion in versions 6.5.0 and above, so earlier versions should fail.
