How to create a PaymentMethod without a pay & How to implement Capture Later

[huangkaichang]

Hi Everyone,

I am coming from the deprecated package. What I need are:

• Let user create a PaymentMethod without any payment.

• Before user start a service request, let user choose a PaymentMethod and the system will place a hold on user
  s PaymentMethod (create a manual capturing PaymentIntent).

• Capture the PaymentIntent when service finish.

The problem is, it seems in current package, to save a PaymentMethod, it always require a payment and the PaymentMethod will be then bind to a customer when the payment success.

Can someone give me some hint?
