Setting NODE_ENV for firebase function : <p>I am moving some of my <code>firebase-queue</code> workers to Firebase Functions. I have used <code>process.env.NODE_ENV</code> to set some of the configuration for the workers depending on the environment in which I am running them. Is there a way to set the <code>NODE_ENV</code> for the functions while deploying them. I understand that the recommended way to provide such config options is via <code>firebase.config.set</code> which I have verified works as expected but just wanted to check if there is a way to set the <code>NODE_ENV</code> also. When I try to print out the <code>NODE_ENV</code> inside of a function, it is always set to <code>production</code>.</p>
