As a user, I want to be able to clearly understand efficiency ratios for all my clusters and comparing one cluster to others, for CPU and memory:

• System used
• OpenShift used
• Applications
• Other

It should be possible to see the costs distributed in one cluster or in multiple clusters.

Specifically:

1. Namespace, node, cluster efficiency score based on usage vs capacity (request is the capacity of a namespace)
2. Namespace, node, cluster efficiency score based on cost used vs total cost of the entity (namespace, node, cluster)
3. Namespace, node, cluster efficiency score based on overhead cost vs capacity cost
4. Namespace, node, cluster efficiency score based on idle vs request (could be negative). Idle is defined as the difference between request and usage (idle = request - usage).

This would be a new tab (the default one) in the Overview page so we'll have three tabs:

• Overview > Dashboard (this new page)
• Overview > OpenShift (existing)
• Overview > Infrastructure (existing)
