             Fix For: 0.1.0


When the Flink operator is installed to non-default namespace these FlinkDeployment manifests [1] may fail to deploy with the following error in the Flink operator log [2]. We may want to remove the `namespace: default` from these manifests and let user specify different one with the --namespace flag in kubectl.
