Import managed cluster failed cause by version conflict on OKD

[xuezhaojun]

After processed these steps:

Step1 : Install community operator from OperatorHub.io
Step2 : Create a Cluster Manager on console
Step3 : Install the managedcluster-import-controller from source files
Step4 : Manually register a cluster

We got error:

E0526 05:51:18.661381       1 lease_controller.go:127] unable to get cluster lease "managed-cluster-lease" on hub cluster: leases.coordination.k8s.io "managed-cluster-lease" is forbidden: User "system:open-cluster-management:cluster1:cv6xm" cannot get resource "leases" in API group "coordination.k8s.io" in the namespace "cluster1"

We fixed it by change all images version in the import.yaml from "latest" to "0.0.3" at Step4

This because hub is 0.0.3 (2.2), but add-on is latest (2.3), we cannot support to use a low version hub to work with high version add-on (the low version add-on can be worked with high version hub)
