f33 has etcd updated to 3.4.13 (see https://koji.fedoraproject.org/koji/buildinfo?buildID=1605511). It's currently not possible to build the same version in f32 due to outdated dependencies in f32:

```
cd /builddir/build/BUILD/etcd-3.4.13/_build/src/go.etcd.io/etcd/clientv3/balancer/picker

Re-assigning to Robert-André Mauchin for further analysis of what is needed and if the rebase is required for f32.
