[EPIC] Roll out a cost attribution system in all AWS clusters

[consideRatio]

This EPIC captures the AWS part of #4384:

Quick intro

The AWS cost attribution system is a simple Python webserver accessing AWS Cost Explorer API to summarize information about an AWS accounts billing data. This summarized billing data is then exposed via a k8s Service, making a Grafana instance able to access it as a datasource. There is a datasource plugin used for this in Grafana called Infinity, as it helps parse the JSON response provided by the webserver. The openscapes grafana instance currently has this system deployed, and the Grafana instance has a Dashboard defined within it that we can re-use.

Kinds of work involved

Most of the AWS specific parts have been done, so now working this epic will mostly involve less cloud specific parts, such as:

• terraform / eksctl
• grafana dashboard development like in jupyterhub/grafana-dashboards
• interaction and communication with openscapes and nasa-cryo community
• the deployer script (Python) and GitHub workflows
• public communication via a blog post

As seen in openscapes

You can inspect the dashboard live at https://grafana.openscapes.2i2c.cloud/d/b4dbba938e548f10/cloud-cost-attribution?orgId=1
