Expected Behavior

Acceptance tests should pass when run against a fresh etcdv3 instance.

Actual Behavior

Acceptance tests fail due to an invalid type conversion.

Steps to Reproduce

1. helm install etcd bitnami/etcd --set auth.rbac.enabled=false (installed in Minikube)
2. kubectl port-forward --namespace default svc/etcd 2379:2379
3. TF_ACC=1 TF_ETCDV3_ENDPOINTS=http://127.0.0.1:2379 go test ./backend/remote-state/etcdv3

Also as a sidenote, is it expected that the etcdv3 acceptance tests do not run when opening a PR that modifies the etcd package?
