Create Kubecost component

[akranga]

I as a user want to deploy a kubecost component through the happy meal

• Happy meal integration
• Ingress with Okta
• Use metadata or role to access spot feed partially supported
• Use terraform bucket as default place. Or arbitrary bucket if needed
• Conditional spot data feed
• Reuse prometheus, grafana behavior
• Kubecost token. flow
• tf imports flow
• extract spot data subscription to a standalone component
• Check kubecost "late binding" on spot data feed
• Concurrent Prometheus configs flow
