Add more properties of persistent volume in the list view

@jigish.addweb

Thanks for your patch. I found some problems below.

1. The claim_ref should be reason.

+  /**
+   * {@inheritdoc}
+   */
+  public function getReason() {
+    return $this->get('claim_ref')->value;

2. It seems that some codes weren't included into the patch.
For example, I can't find where the variable $claim is declared.

+    $entity->setClaimRef($claim);
+    $entity->setPhase($persistent_volume['status']['phase'] ?? '');
+    $entity->setReason($persistent_volume['status']['reason'] ?? '-');

I encountered the following error while executing drush updb since I have unreachable K8s cluster.

$ drush updb -y

I assume the error was caused by the following code.

diff --git a/modules/cloud_service_providers/k8s/k8s.install b/modules/cloud_service_providers/k8s/k8s.install
index ec8dd116..bf9e31f4 100644

+    $k8s_service->setCloudContext($config_entity->getCloudContext());
+    $k8s_service->updateVolumeWithoutBatch();
+  }

Looks we need to validate the K8s cluster connection before start to run $k8s_service->updateVolumeWithoutBatch(); . You can call $k8s_service->getNamespaces(); w/ try-catch clause.

Thank you for the update. I tested it and looks good to me. I'll merge the patch to 8.x-1.x and 8.x-2.x and close this issue as Fixed.
