Add support to pass amqpConnectionOptions through the init options

[saary]

Allow passing amqpConnectionOptions to the constructor function options object.

This is necessary to enable control of specific connection parameters.

Hoping to get this merged as well, as I'd like to send some options to the amqplib module.

Thank you for your fix and my apologies for the delay, This repo got stuck in the void but that's no excuse. I have merged in a fix that should allow you to pass amqpConnectionOptions. I will be hopefully spending some time soon to update and fix any issues with this repo.

If you are using the code directly please let me know if you are still unable to pass amqpConnectionOptions. Otherwise I will work on getting a new npm package up within the week
