      Refactor VM image setup; support extra images; add user import script. · 3b3a8d50

      This cleanly refactors everything we do to VM images (asserting the
      random passwd, disabling root passwd, changing sshd config, etc).  This
      allows us to support adding extra images based on URL/name user provides
      us in params, and to allow them to call our script after profile
      instantiation to add an image.  It's fairly comprehensive and it
      certainly works for the common cloud images from various linux vendors.
      It also rolls multi-nic support into each image.  We do this via
      boot-time udev scripts and dhcp hooks that ensure we don't add routes
      for interfaces other than eth0 (this ensures that the default gateway is
      always attached to eth0).  The old, hacky, sometimes-broken multi-nic
      support is gone, as is the special image.  I have no idea why cloud
      images don't just include this feature by default... it's not hard at
      We support Ubuntu and Fedora/Centos.  We support basically the image
      formats that qemu-nbd supports (i.e., qcow, vmware, vdi, raw), and gz or
      xz compression.  That seems to cover the core spectrum.
      On aarch64, we yank the kernel and initrd out of the image's /boot and
      create an AMI/AKI/ARI image tuple, instead of uploading the raw disk
      image.  I have never figured out how to boot a raw Ubuntu cloud image on
      KVM/aarch64, and the HP guys never got back to me.  So this is the only
      way I know (well, there's UEFI, and there's a UEFI aarch64 BIOS, so the
      UEFI cloud images might work... but life is way too short for all that
