Add PaymentMethod model

[NuckChorris]

Since Braintree has added the ability to use bank accounts for European customers, they've deprecated the CreditCard model in favor of a more source-agnostic PaymentMethod model.

This gem should probably be updated to reflect that

Hi, @NuckChorris
Seems it's still in limited beta, and APIs are subject to change.
Will add it once it's GA.

Thanks!

SEPA is in beta, but the move from CreditCard to PaymentMethod is done and should probably be mirrored here

Good point, will look into it once I got some cycles.

Thanks @NuckChorris !

Just noticed that according to the docs this also applies to Apple Pay, Android Pay, and PayPal. Strangely it doesn't seem that they share many properties, simply that they share a common keyspace

Is anyone already working on this? If not, I might give it a shot, let me know.

@waleedasif322, let me know if you have decided to go for it.

Go 👍 I am no Ruby expert so I willl leave it for someone else, but I would very much appreciate if someone else would make this up to date with current Braintree docs.
