AirFlow Integration [metrics] statsd_datadog_enabled

[nicolamarangoni]

This manual looks obsolete: https://docs.datadoghq.com/integrations/airflow/?tab=host
I'm currently using the following setting:

[metrics]
statsd_datadog_enabled = True

and it looks like

[scheduler]
statsd_on = True

isn't needed anymore, as the metrics are sent to the DogStatsD running per default when the agent is started (on localhost:8125).
Furthermore, the datadog.yaml with the specific settings for AirFlow isn't needed anymore.
However, I don't find any documentation about the parameter statsd_datadog_enabled.
The AirFlow documentation doesn't offer any detail and the is no mention of it in the DataDog docs.

I saw your post on airflow repo as well. Did you figure it out?
