Jira issue: CRDB-68157

Start with multitenant/tenantcostclient.TestConsumptionExternalStorage, especially the backup_from_host_does_not_increment_ingress_or_egress_bytes subtest, and reproduce it with race detection enabled. Inspect the linked test report and captured logs to determine the failure; done means the test passes on master with the expected ingress and egress behavior.
