Description

When we compile the flink-kubernetes-operator, we could find the following overlapping classes of fabric8 kubernetes client dependencies. I propose to add a flink-kubernetes-shaded module to fix this in current project. If we are confident enough the shading works well, I will contribute it to the upstream project Flink.
