feat: introduce list_quorum="auto" to prefer quorum drives (#18084)

NOTE: This feature is not retro-active; it will not cater to previous transactions
on existing setups. 

To enable this feature, please set ` _MINIO_DRIVE_QUORUM=on` environment
variable as part of systemd service or k8s configmap. 

Once this has been enabled, you need to also set `list_quorum`. 

```
~ mc admin config set alias/ api list_quorum=auto` 
```

A new debugging tool is available to check for any missing counters.
