This lets luet to be extended like git does (just by having luet-subcommand binaries under $PATH) following the UNIX filosophy. It has the downside that we silence the errors from cobra and we handle them by ourselves. Also the Exec syscall is not portable, and it should have implementation for each platform (hence why in helpers)
