POL-1405 Replace deprecated Kubecost endpoints for Kubecost Cluster Policy

[midir99]

Description

The endpoint we are currently using has been deprecated “/model/savings/clusterSizing"
It still works but only returns one cluster rather than all clusters.

The new endpoint is returns a different response “/model/savings/clusterSizingETL" and simply adding ETL onto the end of our current end point in the policy returns null values in ds_cluster_sizing

This endpoint returns all cluster recommendations in one response.

Issues Resolved

• Deprecated endpoint from kubecost was replaced.
• https://flexera.atlassian.net/browse/POL-1405

⚠️

cost/kubecost/cluster/kubecost_cluster_rightsizing_recommendations.pt Policy template updated but associated README.md file has not been. Please verify that any necessary changes have been made to the README. Policy Template has indentation issues. Code should be indented with 2 spaces inside each do/end block, info() block, and EOS block, with additional spacing for nested blocks as appropriate: Line 180: Expected indentation of at least two spaces within code/text block. Line 184: Expected indentation of at least two spaces within code/text block. Line 311: Expected indentation of at least two spaces within code/text block. Datasources and scripts with mismatched names found. These names should match; for example, a datasource named ds_currency should be paired with a script named js_currency. This convention should only be ignored when the same script is called by multiple datasources. The following datasource/script pairs have mismatched names: Line 188: ds_cluster_sizing / js_cluster_parse Recommendation policy has export that is missing recommended fields. These fields are scraped by the Flexera platform for dashboards: Line 324: tags

Why are we removing this and all of the calls to it? The intent behind our policy template design is to make the summary template show the name of the applied policy template so that, if the user applies the policy multiple times, they can easily differentiate the different incidents that are raised.

Not sure how removing this is related to replacing deprecated API endpoints.
