GCP Python client method to Create Monitoring Notification channel is not idempotent.

According the documentation it's not possible to handle duplicates directly but you can solve your issue with the following actions :

List the existing notification channels in GCP via the list_notification_channels
Loop on the actual notifications channels (maybe configured in your code), if the element exist in GCP (check from the list retrieved previously), update it via update_notification_channel function, otherwise create it with create_notification_channel function.
