Issue #, if available:

Description of changes:
This change creates the interfaces MqttPublishInterface, MqttSubscribeInterface, and MqttSubscribeHandlerInterface (if you have a preferred name, let me know and I'll change it) which are implemented by MqttClientConnection. The purpose of this change is to enable a change to the IotJobsClient to accept the interface instead of the concrete implementation.

Should this PR be accepted, it should be followed by a change in AWS-IoT-Device-SDK-v2 for the IotJobsClient to use this added interface instead of the concrete implementation.

This PR would resolve #124.

I think this is a good direction. Couple changes I'd like to see, I'll also try and get some others to take a look.

  1. I think we need to also add the handler-less subscribe. I've been told that future IoT Apis may use that function.
  2. I'd like to rename the interface to something that better captures what this is a proxy for (not an entire mqtt connection, but the data pipeline/pubsub part). I'm not sure what a good name is, MqttDataAdapter, MqttPubSubAdapter, etc... Proxy captures it decently, but I think that would be confusing with its other uses. Maybe even MqttDataInterface.

Hi @bretambrose, thanks for the review.

What would you think about having maybe 3 interfaces so that the various use cases can have minimal requirements on the client they are given?

1 interface for pubsub with handler, 1 for pubsub without handler and with global handler, and then 1 which is the same as the concrete implementation?
