Title:
  cloud-init fails to disable ecdsa-sha2-nitp521 keys

Status in cloud-init:
  Fix Released

Bug description:
  cloud-init adds ssh_authorized_keys to the default user fedora and to
  root but for root it disables the keys with a prefix command that
  echoes the helpful message:

  'Please login as the user "fedora" rather than the user "root".'

  However, if the key is of type ecdsa-sha2-nistp521, it is not parsed
  correctly, and the prefix command is not prepended.

  This means that ECDSA keys can be used to login to root.
