Use GetVaultNotifications with an AWS SDK or CLI

The following command gets a description of the notification configuration for a vault named my-vault:

aws glacier get-vault-notifications --account-id - --vault-name my-vault

Output:

{
    "vaultNotificationConfig": {
        "Events": [
            "InventoryRetrievalCompleted",
            "ArchiveRetrievalCompleted"
        ],
        "SNSTopic": "arn:aws:sns:us-west-2:0123456789012:my-vault"
    }
}

If no notifications have been configured for the vault, an error is returned. Amazon Glacier requires an account ID argument when performing operations, but you can use a hyphen to specify the in-use account.
