Disable open tracking & click tracking option at customer account level

To increase chances of landing in primary inbox tab, we can give option to customers to turn off open & click tracking.

Why is it important?

For some clients, landing in primary inbox is more important than tracking link clicks & opens. Turning off open & click tracking definitely help in improving chances of inbox delivery.

I think we already have this option at agency level but it will turn off tracking for all users, we can implement same at customer account level.
