What happened?

Description

Namespace name resource attribute for namespace phase metrics in k8scluster receiver seems to be always empty

Steps to Reproduce

Configure k8scluster receiver and configure pipeline to export metrics from it (for example via Prometheus exporter)

Expected Result

# HELP k8s_namespace_phase The current phase of namespaces (1 for active and 0 for terminating)
# TYPE k8s_namespace_phase gauge
k8s_namespace_phase{k8s_namespace_name="some-namespace-name",k8s_namespace_uid="17484d33-f8e6-4512-bebf-394de39a6278",opencensus_resourcetype="k8s"} 1
k8s_namespace_phase{k8s_namespace_name="other-namespace",k8s_namespace_uid="2a0d3510-f895-4cd9-84ff-cd8078cf7097",opencensus_resourcetype="k8s"} 1
k8s_namespace_phase{k8s_namespace_name="kube-system",k8s_namespace_uid="2ba798ae-2e10-45a1-bd73-60d892349123",opencensus_resourcetype="k8s"} 1

Actual Result

# HELP k8s_namespace_phase The current phase of namespaces (1 for active and 0 for terminating)
# TYPE k8s_namespace_phase gauge
k8s_namespace_phase{k8s_namespace_name="",k8s_namespace_uid="17484d33-f8e6-4512-bebf-394de39a6278",opencensus_resourcetype="k8s"} 1
k8s_namespace_phase{k8s_namespace_name="",k8s_namespace_uid="2a0d3510-f895-4cd9-84ff-cd8078cf7097",opencensus_resourcetype="k8s"} 1
k8s_namespace_phase{k8s_namespace_name="",k8s_namespace_uid="2ba798ae-2e10-45a1-bd73-60d892349123",opencensus_resourcetype="k8s"} 1
