During our Brno meeting we came up with a way of counting registrations by simply tracking the federated links to RedHatExternalProvider with an additional flag describing whether the link was created along a new account or not.
We already have the content indexed into DCP, now we need to write a query that will be compatible with Klipfolio.
Specifically we need something that can return links created with a new account that are aggregated in 3 different time windows daily/monhtly/yearly.
