Warn web developers that card networks as method names are deprecated.

Web developers should use 'basic-card' instead. Deprecated:

  new PaymentRequest(
    [{
      supportedMethods: ['visa', 'amex'],
    }],
    cart);

Should be used:

  new PaymentRequest(
    [{
      supportedMethods: ['basic-card'],
      data: {supportedNetworks: ['visa', 'amex']},
    }],
    cart);

Console warning message:
  [Deprecation] Card issuer network ("amex", "diners", "discover",
  "jcb", "mastercard", "mir", "unionpay", "visa") as payment method is
  deprecated and will be removed in M64, around January 2018. Please use
  payment method name "basic-card" with issuer network in the
  "supportedNetworks" field instead. See
  https://www.chromestatus.com/features/5725727580225536 for more
  details.

This issue has been automatically relabelled type=task because type=launch-owp issues are now officially deprecated. The deprecation is because they were creating confusion about how to get launch approvals, which should be instead done via type=launch issues.

We recommend this issue be used for implementation tracking (for public visibility), but if you already have an issue for that, you may mark this as duplicate.
