Feature Request - Pass options to node websocket

[Lalem001]

I use self signed certs when developing locally, and I need a way of setting the rejectUnauthorized option to false. I would prefer this to disabling such checks globally.

Even setting the ca option could be helpful for production use.

I am willing to make a PR, but do not know how you all would like the options to be passed.

deepstream(url, options);

/**
 * Where options could contain one of the following:
 * options.socket: Object
 * options.socketOptions: Object
 * 
 * or even perhaps:
 * options.rejectUnauthorized: Boolean
 * options.ca: String|String[]|Buffer|Buffer[]
 */
