In https://github.com/java-operator-sdk/java-operator-sdk/pull/1450, we made a copy of fabric8 client [code](https://github.com/fabric8io/kubernetes-client/blob/0742e942eb09f8ed2672f7f82e176b76e595ad50/kubernetes-client-api/src/main/java/io/fabric8/kubernetes/client/Config.java#L817) with slight adaptation. It is suggested to tweak fabric8 API so we don't need to keep this code.
