How to reproduce these conditions

Try and deploy via CircleCI.

Expected behavior

interactive and token should probably be options for the ng deploy option. Otherwise, it is difficult to deploy via CI environments like CircleCI.

Actual behavior

interactive and token cannot be passed through the builder.

I tried using the environment variable $FIREBASE_TOKEN which I think (not sure) logs me in correctly but prompts for analytics. I guess adding only the interactive flag would bypass this but I think token is the recommended method of passing the FIREBASE_TOKEN.
