Equivalent to `aws eks get-token`

### Describe the feature

It would be nice if there was a AWS Java SDK equivalent of AWS CLI's `aws eks get-token`, which I could call to generate a (time-limited) Kubernetes API token for my Java process' current AWS identity similar to:
```json
{
"kind": "ExecCredential",
"apiVersion": "client.authentication.k8s.io/v1beta1",
"spec": {},
"status": {
"expirationTimestamp": "1970-01-01T00:00:00Z",
"token": "k8s-aws-v1.[REDACTED]"
}
}
```

### Use Case

Authenticate to an AWS EKS cluster via its regular Kubernetes HTTP API, without having to create a permanent Kubernetes API token and pass it to the Java process that's already authenticated to AWS.

### Proposed Solution

An officially sanctioned version of e.g. https://github.com/MrBergin/EksX or https://stackoverflow.com/questions/59853623/get-authentication-token-from-aws-eks-using-the-aws-java-sdk-v2.
