Attempt to add/update credit card via Braintree is failing due to lack of 3DSecure support

Current behaviour

When adding a credit card the following errors are observed in the console:

code: "THREEDS_NOT_ENABLED_FOR_V2"
​details: undefined
​message: "3D Secure version 2 is not enabled for this merchant. Contact Braintree Support for assistance at https://help.braintreepayments.com/"
​name: "BraintreeError"
​stack: ""
​type: "MERCHANT"

Expected behaviour

When adding a credit card a flash message appears "Your card was stored successfully" and the card is added correctly to the Braintree payment gateway.

Dev Notes

Customer says this, "Apparently using 3D secure requires using the latest BrainTree SDK which it appears 3Scale isn't using."
According to https://braintree.github.io/braintree-web/current/three-d-secure_shared_errors.js.html
THREEDS_NOT_ENABLED_FOR_V2: Occurs when 3D Secure component is created with version 2 parameter, but merchant is not enabled to use version 2.
