      Especially libvnode_docker::analyzeImageWithBusyboxCommand, which runs
      the busybox-static binary from the root context in the container with
      the given command (and extra container run API configuration).

      Docker clientside update: use our perl API lib instead of cli and cURL. · 57089d52
      David Johnson authored
      (Of course, there is no standard perl Docker Engine API, so I wrote my
      own thin perl library, basically error handling and JSON marshalling
      goo.  But had to deal with LWP/http over UNIX socket to Docker, which
      is whacky; fortunately, there was a module, but I can confirm that LWP
      is a pain when you get off the beaten track.  Anyway, I added a little
      client that is useful for debugging.)
      
      Also, I refactored things a bit so there is now an emulabize-image
      script that can be run to test emulabization of docker images
      separately from vnode creation.
      
      Also, add a specific Docker version of the prepare script.  This
      actually gets run in image commit as an ONBUILD instruction.
      
      Also, always copy the image's master passwd files into /etc/emulab
      instead of using those installed by client-install.  Those just don't
      apply at all here since we have no idea what the base image is; the
      uids/gids in the clientside dirs could be a complete mismatch for the
      image.
