Feature flag: ci_job_artifacts_backlog_work
Control execution of our new artifact-backlog-work service by turning
Ci::JobArtifacts::UpdateUnknownLockedStatusService into a no-op.

Feature flag: ci_job_artifacts_backlog_large_loop_limit
Control the number of rows updated in or removed from
ci_job_artifacts in a single execution by increasing the loop_limit
from 100 ot 500 iterations. BATCH_SIZE = 100 implies a record limit
for a single worker execution of 10,000 or 50,000 rows.

First, we need to remove the DISTINCT clause from this query. Using
it tried to distinct the whole table before applying the limit, which
is bad. Also, using DISTINCT implicitly queried for the lowest job_id
values first, which created an enormous pile of dead tuple at the end
of the index that we were explicitly starting our query from. This is
catastrophic for index performance on replicas, but not on the
primary, which can use LP_DEAD hint to skip dead index tuples. On
replicas, performance remains degraded until we VACUUM.

Second, we apply an explicit order by expiration to prevent us from
accidentally querying rows in an order that correlates with job_id.
By ensuring that we query rows that are generally well-distributed
across the table, we prevent large blocks of dead index tuples that
need to be scanned before we can come up with 100 live tuples to
return.

Third, we destroy unlocked job artifacts without updating.
By updating rows in ci_job_artifacts to then be deleted on the next
loop cycle, we create twice as many dead tuples as necessary in the
table. Artifacts locked by ci_pipelines.locked will be updated and
left in place, but the others will get passed directly into the
DestroyBatchService to be removed. The dead tuple created by the
update is not necessary.
