[GCP] Add billing additional fields

[gpop63]

Overview

This change introduces new billing fields and fixes the aggregation functions in the billing dashboard lenses.

Previously, the max aggregation was used, since the granularity of the billing data was low. Due to increased granularity which produces multiple documents per day, the sum aggregation is appropriate for accurately displaying total costs.

Fields added:

• sku_id
• sku_description
• service_id
• service_description
• effective_price
• tags (nested)
  • key
  • value

With these additional fields, we can add new lenses to improve the insight into billing data. This should be handled in a separate enhancement PR.

Following the merge of elastic/beats#36902, we can proceed with this PR.

The change looks good; I only have one question and one nit.

Question

The PR on Beats introduced a detailed usage cost table alongside the existing standard table. IIRC, users must use the detailed table pattern to get the extra fields.

How do integration users get standard vs. detailed usage cost data? Should they use the detailed table pattern as well?

If users get standard vs. detailed usage cost data by setting the table pattern, we should describe this behavior in the docs and give a hint in the setting description in the UI.

Nit

We should include tag values in the sample document.

[zmoog]

nit: It would be helpful to include tag values in the sample event.

Thanks for the docs update!
