Preparing package for MOTU inclusion

  debian/:
    - Add overrides to the init.d issues even though we only provide .upstart
    file
    - Make sure all templates are translatable
    - Alter packaging to have a metapackage "cloud-install" and several
      dependency packages (eg. "cloud-install-common")
  Closes "needs-packaging" bug (LP: #1282837)
