Description

Add support for Samsung Pay through Adyen.

Steps for Samsung Pay:

1. Download samsung sdk, after following some sdk calls, sdk gets payment token.
2. This payment token is passed in confirm call
3. We get direct terminal status from Adyen

Api contract for samsung pay :

    "payment_method": "wallet",
    "payment_method_type": "samsung_pay",
    "payment_method_data": {
        "wallet": {
            "samsung_pay": {
                "token": "fghjkmgdfghjkl;dfghjkl;'mbedjsnjfkcnk"
            }
        }
    },
