Create a dataset with a customer-managed encryption key

The following example creates a dataset named `mydataset`, and also uses the `google_kms_crypto_key` and `google_kms_key_ring` resources to specify a Cloud Key Management Service key for the dataset. You must enable the Cloud Key Management Service API before running this example.
