nit: since you saying for user, nice to include tenat-id as well in the error log?

I think that should be covered by the spanlogger: https://github.com/grafana/dskit/blob/ebb5c6de233d26951aef41eada3cab3295ecb368/spanlogger/spanlogger.go#L99-L111

To avoid showing deleted data, the querier originally failed when deletes were unavailable. If the compactor becomes unavailable this can cause Loki to stop responding to queries altogether. This PR changes the querier to log an error but continue servicing the request when it fails to get deletes. Extends PR #6368 Signed-off-by: Christian Haudum <christian.haudum@gmail.com>

To avoid showing deleted data, the querier originally failed when deletes were unavailable. If the compactor becomes unavailable this can cause loki to stop responding to queries altogether. This PR changes the querier to log an error but continue servicing the request when it fails to get deletes.
It also adds metrics to the
delete_requests_clientso we can alert when there is a chronic failure to get delete requests.
