Cannot configure pull secrets, so cannot use it at all

Hi thanks for the lib! However, we cannot configure the pull secrets, so cannot use it.

We use the openebs helm chart + jiva helm chart to deploy it. Then we create a PVC with jiva's storage class. Then new pods are created: pvc-bb6efceb-e7b0-4d1f-ae64-5dd2c0fa6aeb-jiva-ctrl-fbb5bf7dc989 and pvc-bb6efceb-e7b0-4d1f-ae64-5dd2c0fa6aeb-jiva-rep-0. However, the two pods does not have pull secrets specified, so the container image cannot be pulled at all (we cannot use the image at docker hub but has to use some private registry with pull secrets instead).
