Notifier updates in 7.2.0

[expFlower]

We're in the process of updating our version of the controller from 6.1.0 and i'm comparing the differences. I can see the you've added a new section the Notifiers configuration: specifically:

datadog:
    enabled: true/false # enables the datadog notifier

However when i look at the configmap there's no mention of the new section? 😕
