The script package is a great tool to use for testing and even runtime debugging, especially when used as REPL such as with the break command or in cilium-db shell. It would be nice if we could implement autocomplete for the commands.

The term package which we use when dropping into REPL already has support for an auto complete callback.

This would be great to have for commands themself, for example being able to type re<tab> and it autocompleting to replace. But perhaps more useful would be per-command completion as well. So doing cmp <tab> would list out available files and cycle through them. And commands such as those implemented by cilium/statedb could suggest table names ect.
