Drivegroup's :limit: isn't working correctly
Each iteration of an osd deployment deploys OSDs up to a set :limit:
Since we're deploying every $sleep_interval seconds it will eventually deploy all OSDs.
We need to factor in the already deployed nodes when working with the :limit: directive.
To properly find out which osd was being deployed by which drivegroup we need to address https://tracker.ceph.com/issues/44755 first.
