Add device information in AJO tracking Dataset

[#1]

Description - device information (user Agent) in the tracking dataset

Why is this feature important to you - It will give us ability to track if users are more on Mobile or Desktop. Also help to debug in case of clicks not reaching landing pages if the failures are related to mobile or web browser. It will also help to ghost opens (Apple Mail Privacy) from real openers

How would you like the feature to work - Getting the details into tracking dataset. Add a report on a breakdown of open and clicks per operating systems, devices and browsers will be a plus

Current Behaviour - None

Thanks,

David
