Title:
  SSH module to generate ed25519 host keys

Status in cloud-init:
  New

Bug description:
  Hi,
  Since openssh-server 6.5 there is support for a new host key, ed25519. It appears that cloudinit 0.7.6 doesn't generate this; ed25519 is not listed as a valid key type in ssh_util.py. Is this correct that cloud init doesnt generate this host key, and if so, should this be supported? Generation is easy, on new versions of openssh-server:

  ssh-keygen  -f /etc/ssh/ssh_host_ed25519_key -N '' -t ed25519

  Thanks.
    James
