How to enable SSH password authentication on Fedora CoreOS

Add this config line to your Fedora CoreOS Ignitionconfig in order to enable SSH password authentication on your install.

  files:
    - path: /etc/ssh/sshd_config.d/20-enable-passwords.conf
      mode: 0644
      contents:
        inline: |
          PasswordAuthentication yes

By default, Fedora CoreOS will only allow pubkey authentication and disable password authentication. This Ignition config will set PasswordAuthentication yes as a config option for the SSH daemon.
