When submit Spark engine to Kubernetes environment, `org.apache.kyuubi.engine.KubernetesApplicationOperation#getApplicationInfoByTag` will use Kubernetes client to get driver pod info, if we do not set `spark.kubernetes.context`configuration in Spark environment, `org.apache.kyuubi.config.KyuubiConf#getKubernetesConf` will construct a client with **default** namespace, this will cause privilege problem if Kyuubi running with a partial rolebinding service account:
```log

Message: pods is forbidden: User "system:serviceaccount:kyuubi:kyuubi" cannot list resource "pods" in API group "" in the namespace "default". Received status: Status(apiVersion=v1, code=403, details=StatusDetails(causes=[], group=null, kind=pods, name=null, retryAfterSeconds=null, uid=null, additionalProperties={}), kind=Status, message=pods is forbidden: User "system:serviceaccount:kyuubi:kyuubi" cannot list resource "pods" in API group "" in the namespace "default", metadata=ListMeta(_continue=null, remainingItemCount=null, resourceVersion=null, selfLink=null, additionalProperties={}), reason=Forbidden, status=Failure, additionalProperties={}).
```
This will appear as engine startup failure, but in fact the engine is started successfully.
## Describe Your Solution 🔧
`KyuubiConf.getKubernetesConf` method should set namespace even if the Kubernetes context is empty, please see the commit.
