using options object and handle error inside module when handleError …

[doron2402]

1. change options to an object.
2. add handleError (we had issue on production)

the issue was that one of our statsd server url was change and the whole app crash
{ [Error: getaddrinfo ENOTFOUND] code: 'ENOTFOUND', errno: 'ENOTFOUND', syscall: 'getaddrinfo' }

I fix it using domain but that's seems like a good solution that you could listen to the socket and disable it from returning an error.
