Three doc Question?

##### ISSUE TYPE
* Documentation Report
* Other

##### COMPONENT NAME
- Cloudsatck Baremetal Management
- CloudStack Kubernetes Service

##### CLOUDSTACK VERSION
- CloudStack 4.18.0.0

1. Does CloudStack Baremetal can only work in basic networking mode currently? (https://cwiki.apache.org/confluence/display/CLOUDSTACK/Baremetal+Advanced+Networking+Support)


2. Is there any doc about how to use cloudstack to manager the Baremetal servers? I can not find the useful info in the official doc. I only find: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Baremetal+KickStart

3. As http://docs.cloudstack.apache.org/en/latest/plugins/cloudstack-kubernetes-service.html#kubernetes-clusters mentioned, (With CoreOS having reached EOL, from 4.16 the Kubernetes Service Plugin will use the existing SystemVM template for deploying kubernetes clusters. ), does the cloudstack can deploy kubernetes clusters using self defined template? If supported, How to build a self defined template?

先從連結的 Baremetal Advanced Networking Support、Baremetal KickStart 和 Kubernetes Service 文件開始，然後將其與 issue 中的三個問題進行比較。當文件清楚涵蓋 Baremetal 網路與管理，並說明是否可以為 Kubernetes 叢集使用和建置自訂範本時，即表示完成。
