[BUG]why OpenSearchGenericClient.withTransportOptions(TransportOptions transportOptions) create a new OpenSearchGenericClient object?

[swxEmily]

What is the bug?

A clear and concise description of the bug.
OpenSearchGenericClient.withTransportOptions(TransportOptions transportOptions).execute(Request request) create a new OpenSearchGenericClient in every execution.

How can one reproduce the bug?

Steps to reproduce the behavior.

1. Create OpenSearchTransport with global connection timeout settings. And create OpenSearchGenericClient.
2. Most requests use global connection timeout settings to access the server by OpenSearchGenericClient.execute(Request request).
3. Some special requests need custom connection timeout settings to access the server by OpenSearchGenericClient.withTransportOptions(TransportOptions transportOptions).execute(Request request).

private static void search(OpenSearchGenericClient client, String endPoint, long connectionTimout) {
Request request = Requests.create("GET", endPoint, null, Map.of(), null);
ApacheHttpClient5Options transportOptions = ApacheHttpClient5Options.DEFAULT.toBuilder()
.setRequestConfig(
RequestConfig.custom().setConnectionRequestTimeout(connectionTimout, TimeUnit.SECONDS).build())
.build();
try {
// each request set connectionTimeout independently
Response response = client.withTransportOptions(transportOptions).execute(request);
System.out.println(response);
} catch (IOException e) {
throw new RuntimeException(e);
}
}

What is the expected behavior?

client.withTransportOptions(transportOptions) create a new OpenSearchGenericClient, each request will create a new client object, it will create many temp client objects
