The kubeconfig explicit path is not updated correctly when supplied through the --kubeconfig flag in kubefed init. This leads to the details about the initialised federation control plane not getting updated in the correct kubeconfig file.
**Special notes for your reviewer**:

**Release note**:
```
Fixed a bug that caused the kubeconfig entry for the initialized federation control plane to be not written to the supplied kubeconfig file when the file was supplied through the --kubeconfig flag.
