Timeouts on requests

[acasas]

Are you guys considering adding timeouts to the requests made in the library? My understanding is that there is no timeouts in superagent, and therefore some requests might never end, which is something that I am seeing happening in mobile env with not a great connectivity.

A possibility would be to extend the Defaults with a timeout, that would be applied to the request in the _request(), and that I could override when creating the Particle object in my app:

particle = new Particle({
    baseUrl: 'https://api.particle.io',
    clientSecret: 'particle-api',
    clientId: 'particle-api',
    tokenDuration: 7776000, // 90 days
    timeout: 5000
  });
