What happened?

On airflow UI, Admin > Variables
When we export variables and save the JSON, it does not include description field. So when imported in another environment, description field has to be updated manually.

At that moment (and historically) Airflow save variables (both in UI and CLI) as key-value storage, and if the values is a valid python dictionary than it serialize as json object

{
    "Variable 1": "Values"
    "Variable 2": {
        "spam": "egg"
    }
}

Without changing the format it is not possible to achieve add description in other words someone need to introduce version 2 of variables dump format and Airflow should able to work with both of them for backward compatibility.
