[8.15] Endpoint data volume reduction mechanisms [ESS] (backport #5881)

[mergify]

Contributes to #5771.

Currently ESS only – serverless content will be added later. Per Slack conversation:

We should publish serverless later because this won't be available to customers in Serverless until after 8.18/9.0 ship since it depends on Endpoint changes
