This parameter is not used any more, and has caused a lot of confusion.
In the distant past, the dashboard was used at Mapzen to track progress of builds. As part of this, a Redis instance stored how many documents were seen in the previous build (Mapzen had a dedicated build cluster), and used that to compare against.
The auth token was use to access this Redis instance.
Because that workflow was heavily integrated into Mapzen's infrastructure, and isn't really relevant to how we generally suggest setting up Pelias these days, it's best to remove it all.
