TL;DR: when reporting a cost, report also the constituents of that cost, e g. usage, taxes, savings plan & enterprise discount

It's essentially "give me the total cost and the itemization too". We should do this everywhere, not just for AWS amortized and unblended.

Users want this also as part of ROS for OpenShift: "project X has costed $700 USD in February because it of <amount> in compute, <amount> in storage, <amount> in networking, <amount> in ROSA marketplace, <amount> in taxes, <amount> in savings plan, <amount> CPU core hours, <amount> RAM GB hours, <amount> ROSA subscription dollars, etc". 

One key part we are missing here is custom costs, ie costs coming from a price list: users create an itemized price list but then we lump that together and never return the categorization back.
