enhancement: Retries if connection fails

[aboccardi]

In realtime.js if connection to iot platform fails there is no retry.

var connectOptions = new Object();
connectOptions.keepAliveInterval = 3600;
connectOptions.useSSL=true;
connectOptions.userName=api_key;
connectOptions.password=auth_token;

connectOptions.onSuccess = function() {
	console.log("MQTT connected to host: "+client.host+" port : "+client.port+" at " + Date.now());
}

connectOptions.onFailure = function(e) {
	console.log("MQTT connection failed at " + Date.now() + "\nerror: " + e.errorCode + " : " + e.errorMessage);
}
console.log("about to connect to " + client.host);
client.connect(connectOptions);

Would it be connectOptions.onFailure = function(e) { .... } (line 60 of realtime.js) the right place to handle retry logic?

Sorry if it's a silly question but I don't have much javascript experience.
