Add Identity and Metadata to Messages

[Mulkave]

In order to identify producers, it could be helpful to have a proprietary message object that includes the body (data) that is usually sent by the user. A better way to explain this is through an example:

Producer A sends a BowlerMessage or BowlerMessageBody where the AMQPMessage's body property is the message body itself. That message contains the body and other metadata in a JSON format as such:

{
    "created_at": "DATETIME",
    "send_at":  "DATETIME",
    "body": "ENCODED JSON USER DATA",
    "producer": {
        "ip": "192.168.0.1",
        "name": "Facebook Ads Service",
        "subject": "Facebook Ads Estimated Reach - Audience Size",
        "queue_name": "facebook_ads_estimated_reach"
     }
}

The above is just an example to illustrate the idea, names and structure may change.
