Geo: Secondaries are orphaning artifact files

Problem

Since the release of parallel delete of job artifacts in 13.6 any artifacts which are deleted in this manner (nearly all of them) become orphaned on Geo secondaries.

Proposal

If fixing this before Job artifacts are migrated to the Geo framework:

• Add bulk insertion of Geo::JobArtifactDeletedEvent records during https://gitlab.com/gitlab-org/gitlab/-/blob/v13.7.3-ee/ee/app/services/ee/ci/destroy_expired_job_artifacts_service.rb#L11.
• Add bulk insertion of Geo::JobArtifactDeletedEvent records during https://gitlab.com/gitlab-org/gitlab/-/blob/v13.7.3-ee/app/services/ci/destroy_pipeline_service.rb

If fixing this during &3114 (closed) then don't use Geo::JobArtifactDeletedEvent. Make new events on the JobArtifactReplicator class e.g. :pipeline_deleted and job_artifact_batch_deleted.

Workaround

Occasionally run a rake task on each secondary site https://docs.gitlab.com/ee/raketasks/cleanup.html#remove-orphan-artifact-files
