Cloud Spend Aggregator: Unified Metrics for Cost & Application Insights

The Cloud Spend Aggregator (CSA) extracts cost and usage data from various sources, maps these to AEP fields, and ingests the result to Customer Journey Analytics (CJA). The main purpose of the aggregator is to lay down cost metrics (like CloudEfficiency, Ethos Chargeback, and CMDB) side by side with application metrics (like Prometheus, OpenTSDB), and use the power of CJA to combine them.
