migrate endpoint out of service - have-i-been-powned

[raphaelgavache]

The endpoint called by the crawler is set to service, migrating this out to an explicit attribute.
This migration would need to be done in 3 phase:

1. migrate the assets here
2. change the crawler to avoid adding @service
3. cleanup the asset (service-remapper and attribute-remapper)

Motivation

Review checklist (to be filled by reviewers)

• Feature or bugfix MUST have appropriate tests (unit, integration, e2e)
• Add the qa/skip-qa label if the PR doesn't need to be tested during QA.
• If you need to backport this PR to another branch, you can add the backport/<branch-name> label to the PR and it will automatically open a backport PR once this one is merged
