Cost Explorer API (14/n): Refine next sprint issues

[consideRatio]

At this point, we need to get more issues refined so that they are getting planned rather than unplanned in order to minimize unplanned work.

Definition of done

• Sufficient (intentionally vague) issues are refined for a future 1 week sprint

[consideRatio]

Done with the refinement of issues:

• [EPIC] Roll out a cost attribution system in all AWS clusters #4872
• AWS cost attribution (1/4): write documentation on how to deploy the system to another community #4873
• AWS cost attribution (2a/4): deploy to nasa-cryo #4874
• AWS cost attribution (2c/4): convert Grafana dashboard into a .jsonnet template and version control it #4875
• AWS cost attribution (2d/4): automate deployment of the grafana dashboard definitions #4876
• AWS cost attribution (3/4): deploy to all other AWS clusters #4878

Labelled this as unplanned, but it was meant to be planned but we ran out of time during the iteration planning meeting.
