[FEATURE] Vaulting a payment method

[tinu-hareesswar]

Feature Description

This will be the tracking issue for all Vaulting related changes.

Problem Statement

Currently, the only way a merchant can vault a card for one of his customers is through processing a payment for that customer with a setup_future_usage preference given. We want to enable the merchant to be able to vault a card for a customer through the SDK without having to process a payment.

Although there are APIs for this very purpose, it is not compatible with the SDK since it operates only with a payment client secret.

@tinu-hareesswar This internal developer assistance document would help us a lot, without a doubt. Can't share?
