Feature : Allow configuration options to be passed into Client constructor

[iamchrismiller]

It would be nice to be able to allow Client constructor options. We would have to define the default options block for each worker since they will all be different and validate against bad options.

Maybe we can define a config json with a parameter

-e Environment Config

env-socketio.js

{
   "connect timeout" : 2000,
   "reconnection delay" : 200
}
