  [udev] FIDO u2f security keys should be supported out of the box

Status in systemd source package in Xenial:
  Fix Committed

Bug description:

   * Users plugin U2F key and it does not work in Google Chrome

  [Test Case]

   * Have stock ubuntu install, without custom U2F rules or libu2f-host0

   * Use U2F factor authentication website e.g. google apps, github,
  yubico, etc.

   * Pluging in the key, should just work and complete U2F
  authentication instead of timing out

  [Regression Potential]

   * Should not conflict with libu2f-host0 udev rules which is where
  these are currently shipped

  FIDO u2f is an emerging standard for public-private cryptography based
  2nd factor authentication, which improves on OTP by mitigating
  phishing, man-in-the-middle attacks and reply attacks.

  Google Chrome supports u2f devices which are now widely available from
  Yubico (new premium neo Yubikeys and Security keys).

  However, udev rules are required to setup permissions to allow the
  web-browsers which are running as regular users to access the devices
  in question.


  KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0664", GROUP="plugdev",
  ATTRS{idVendor}=="1050", ATTRS{idProduct}=="0113|0114|0115|0116|0120"

  Something like that should be enabled by default, however probably not
  encode on the vendor/productid as other vendors will also make u2f
