Backport
This PR is auto-generated from #16305 to be assessed for backporting due to the inclusion of the label backport/1.5.x.
The below text is copied from the body of the original PR.
In Nomad 0.12.1 we introduced atomic job registration/deregistration, where the new eval was written in the same raft entry. Backwards-compatibility checks were supposed to have been removed in Nomad 1.1.0, but we missed that. This is long safe to remove.
