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?

先从链接的 Baremetal Advanced Networking Support、Baremetal KickStart 和 Kubernetes Service 文档开始，然后将其与 issue 中的三个问题进行比较。当文档清楚地涵盖 Baremetal 网络和管理，并说明是否可以为 Kubernetes 集群使用和构建自定义模板时，即表示完成。
