Auto-Join issues with Kubernetes

[rclayton-the-terrible]

When using the Helm chart, we cannot specify more than 3 server.replicas for server nodes or the cluster will not bootstrap (I've tried multiple times).

The workaround is to install the cluster:

helm install --name dkron ./dkron-helm

When the cluster is formed, bring up additional server nodes one at a time:

kubectl scale deployment dkron-server --replicas=4
# Watch logs to make sure they come online
kubectl scale deployment dkron-server --replicas=5
# Watch again.
