katib: Can not find experiments in frontend if namespace is not kubeflow

/kind bug

What steps did you take and what happened: I am new to katib and not sure if this is an issue.

Based on my finding, I notice if I submit experiments in different namespaces other than kubeflow. There’re two problems

1. Can not find experiments on UI
2. Sometimes experiment never get done. Seems pod are done but experiment status are not updated. Checked status using command kubectl get experiments

What did you expect to happen: We want every individual user create experiment in their own namespace.

Environment:

• Kubeflow version: 0.6.2
• Kubernetes version: (use kubectl version): 1.13.8
