API server `--standalone-mode` doesn't work

[wallrj]

Trying to run the navigator API server locally but found that even with the --standalone-mode flag, it still requires Kubernetes API host, port and token.

./navigator-apiserver_linux_amd64 --etcd-servers http://127.0.0.1:38501 --standalone-mode --secure-port 0

      --standalone-mode                                         Standalone mode runs the APIServer in a mode that doesn't require a connection to a core Kubernetes API server. For example, admission control is disabled in standalone mode.
