Hi Team,

Is there any API where i can utilize to delete the cluster settings?

I have configured the cluster settings to use sniff mode but when i tried to change that to proxy mode, i am getting error that its already configured with sniff mode and cannot be changed to proxy mode.

```auto
curl -X PUT "http://a.b.c.d:31777/_cluster/settings" -H 'Content-Type: application/json' -d'
> {
> "persistent" : {
> "cluster" : {
> "remote" : {
> "elasticsearch" : {
> "mode": "proxy",
> "proxy_address": "x.y.z.4:31781"
> }
> }
> }
> }
> }'
{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Setting \"cluster.remote.elasticsearch.seeds\" cannot be used with the configured \"cluster.remote.elasticsearch.mode\" [required=SNIFF, configured=PROXY]"}],"type":"illegal_argument_exception","reason":"Setting \"cluster.remote.elasticsearch.seeds\" cannot be used with the configured \"cluster.remote.elasticsearch.mode\" [required=SNIFF, configured=PROXY]"},"status":400}[dsadashivaia@target ~]$

```

Yes, you set unwanted settings to `null` using the very same API. See [these docs](https://www.elastic.co/guide/en/elasticsearch/reference/8.7/cluster-update-settings.html) for more information.

Thanks @DavidTurner

For other folks information adding sample payload as well:

```auto
curl -X PUT "http://x.y.z.e:9200/_cluster/settings" -H 'Content-Type: application/json' -d'
{
  "persistent" : {
  "cluster.*" : null 
  }
}'

```
