[OSSTEST PATCH 23/35] netboot: Introduce TftpNetGrub*

[Ian Jackson <ian.jackson@eu.citrix.com>]

* When expanding netboot filenames, look for NetGrub config keys
  rather than Pxe filenames.  Currently this only affects mg-hosts
  because the files are created by setup_grub_efi_bootcfg, and the
  files are of course referred to only by the actual netboot grub
  image (which may be made by mg-netgrub-loader-update: neither of
  which honour these variables.

* Update the documentation, the default configs, and the
  production-config-*.
