Daniel Nephin 047abdd73c acl: remove ACLDatacenter
This field has been unnecessary for a while now. It was always set to the same value
as PrimaryDatacenter. So we can remove the duplicate field and use PrimaryDatacenter
directly.

This change was made by GoLand refactor, which did most of the work for me.
