is not LEARNER

Steps To Reproduce:

• Installed K3s:
• Installed etcdctl
  ETCD_VERSION="v3.5.5" ETCD_URL="https://github.com/etcd-io/etcd/releases/download/${ETCD_VERSION}/etcd-${ETCD_VERSION}-linux-amd64.tar.gz" curl -sL ${ETCD_URL} | sudo tar -zxv --strip-components=1 -C /usr/local/bin
  etcdctl member list --cacert=/data/k3s/server/tls/etcd/server-ca.crt --cert=/data/k3s/server/tls/etcd/client.crt --key=/data/k3s/server/tls/etcd/client.key --write-out="table"
  is not LEARNER

Additional context / logs:

[dereknola]

Once servers successfully join the cluster, they are no longer learners, but full members. There isn't a problem with the setup you are describing. See https://etcd.io/docs/v3.3/learning/learner/#raft-learner

You can also see it joining as learner and being promoted to full voting member, if you check the k3s logs.
