extend server config.yaml to support per pool set drive count (#19663)

Browse Source 
This is to support deployments migrating from a multi-pooled
wider stripe to lower stripe. MINIO_STORAGE_CLASS_STANDARD
is still expected to be same for all pools. So you can satisfy
adding custom drive count based pools by adjusting the storage
class value.

```

address: ':9000'
rootUser: 'minioadmin'
rootPassword: 'minioadmin'
console-address: ':9001'
pools: # Specify the nodes and drives with pools

        - 'node{11...14}.example.net/data{1...4}'

    set-drive-count: 6

If you are using the config `v1` YAML you should migrate your `pools:` field values to the following format
`v1` format
```yaml
pools: # Specify the nodes and drives with pools
-
- "https://server-example-pool1:9000/mnt/disk{1...4}/"
- "https://server{1...2}-pool1:9000/mnt/disk{1...4}/"
- "https://server3-pool1:9000/mnt/disk{1...4}/"
- "https://server4-pool1:9000/mnt/disk{1...4}/"
```
to `v2` format
```yaml
pools:
- args:
- "https://server-example-pool1:9000/mnt/disk{1...4}/"
- "https://server{1...2}-pool1:9000/mnt/disk{1...4}/"
