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?

Start with the linked Baremetal Advanced Networking Support, Baremetal KickStart, and Kubernetes Service documentation, then compare them with the three questions in the issue. Done means the documentation clearly covers Baremetal networking and management and explains whether self-defined templates can be used and built for Kubernetes clusters.
