问题是什么
目前1台虚拟机是master节点，3台物理机是worker节点。
期望：高可用集群
疑问：
1.是否可以将3台物理机设置为即使master节点也是worker节点？
apiVersion: kubekey.kubesphere.io/v1alpha1
kind: Cluster
metadata:
name: config-sample
spec:
hosts:
{name: master1, address: 192.168.60.152, internalAddress: 192.168.60.152, user: root, password: P@ssw0rd}
{name: master2, address: 192.168.60.153, internalAddress: 192.168.60.153, user: root, password: P@ssw0rd}
{name: master3, address: 192.168.60.154, internalAddress: 192.168.60.154, user: root, password: P@ssw0rd}
roleGroups:
etcd:
master1
master2
master3
control-plane:
master1
master2
master3
worker:
master1
master2
master3
2.如果这样设置，访问入口是否就是master1节点，那如果master1节点故障，如果保持高可用呢？
