Creating payment method arguments documentation are different from this library

[dbarzdys]

While programming I found that PaymentMethodParams struct contains Customer

stripe-go/paymentmethod.go

Line 69 in 405d49f

Customer *string `form:"customer"`

But API documentation does not list it under allowed arguments
https://stripe.com/docs/api/payment_methods/create?lang=go

How does it work? Does it automatically attaches customer to new payment method or is it not even used for creating new payment methods?

@dbarzdys Sorry about the confusion here. You're right that this parameter does not work in the API. You have to create the PaymentMethod and then separately attach it to a Customer

Opened a PR to clearly mention this parameter never worked and we will remove it in the next major version!

Removing this parameter removed the possibility to share a payment-method from a platform-account to a connected account.

After recommendation from "@karllekko" on #stripe on freenode IRC, a workaround is to use https://godoc.org/github.com/stripe/stripe-go#ExtraValues to manually add the Customer-parameter back.

Maybe another endpoint should be created for sharing payment-methods that take a ClonePaymentMethodParams/PaymentMethodCloneParams struct or similar?

Opened a fix in #983 sorry for the trouble here
