**What would you like to be added**: Add an optional endpoint for serving PXE binaries via tftp using e.g. https://github.com/pin/tftp. I would recommend to have a flag like: `--enable-tftp` + `--tftp-artefacts-dir` which will be exposed via the tftp handler. **Why is this needed**: This will dramatically simplify the deployment as there is no need to run tftp on the side. /cc @damyan @hardikdr
