Environment variable for the admin cluster kubeconfig file

Several gkectl commands require the path of the admin cluster kubeconfig file. You can specify the path by exporting a GKECTL_KUBECONFIG environment variable. For example:

export GKECTL_KUBECONFIG=/path/to/my-admin-cluster-kubeconfig

If you do not export the GKECTL_KUBECONFIG environment variable, then you must use the --kubeconfig flag when you run the command.
