hard coded auth key leaking to new <action>

origin: kubernetes-sigs/kui#468

I'm not sure why this is hardcoded - it's not really guaranteed to be true for local deployment and leads to surprising results.

On new x, and then clicking deploy, the authentication header sent is this hard coded key even though auth add .... was done explicitly. The best I can figure so far is that maybe this key is somehow leaking threre.
