Document and Visualize Infrastructure and Hardware requirements for Hosted Control Planes

Overview 

HyperShift is being consumed by multiple providers. As a result, the need for documentation increases especially around infrastructure/hardware/resource requirements, networking, .. 

Goal

Before the GA of Hosted Control Planes, we need to know/document:

• What Infrastructure is managed by HCP?
• What are the hardware requirements/prereqs for a hosted cluster?
• What infrastructure resources get created by Kubernetes/OpenShift during hosted cluster lifecycle?
• What networking requirements exist, e.g., open ports? 
• What are storage requirements?
• What default quota limits are there (e.g., EIP default limits per region)? Do we tell the user to increase them in production? 

DoD

The above questions are answered for all platforms we support, i.e., we need to answer for

• [x] AWS 
• [x] Baremetal via the agent
• [x] KubeVirt
