can't seem to find a place to use my oauth client id / client secret

[dmiddlecamp]

we should support this in addition to tokens, since the console only supplies client_id / client_secret for product creators.

Right now the only place for client id and secret are used is in login():

const particle = new Particle({ clientId: 'my-client', clientSecret: 'my-secret' });
particle.login({ username: 'me@example.com', password: 'sekrit' }).then(() => console.log('yay!'));

Are there other places where it can be used?
