**[CONTEXT]** is optional, if not set, then the current context specified in kubeconfig will be used.
It supports TLS, username and password, or token-based authentication.
This option is ignored if connecting in-cluster (i.e., the endpoint is not specified).
* `apiserver_qps` **QPS** sets the maximum queries per second (QPS) rate limit for requests.
This allows you to control the rate at which the plugin sends requests to the API server to prevent overwhelming it.
* `apiserver_burst` **BURST** sets the maximum burst size for requests.
This allows temporary spikes in request rate up to this value, even if it exceeds the QPS limit.
* `apiserver_max_inflight` **MAX** sets the maximum number of concurrent in-flight requests.
This caps the total number of simultaneous requests the plugin can make to the API server.
* `namespaces` **NAMESPACE [NAMESPACE...]** only exposes the k8s namespaces listed.
If this option is omitted all namespaces are exposed
* `namespace_labels` **EXPRESSION** only expose the records for Kubernetes namespaces that match this label selector.
