Add completions for go and rust tools

I possibly can implement it, but don't guarantee I will do it quickly.

It might be covered if we implement chrisant996/clink-gizmos#11

That issue has a misunderstanding about how parsers work and/or about how different the help layout and syntax is for different programs.

It isn't really possible to make a generic parser that magically handles all programs' help text without knowing anything specific about the programs or their help text formatting.

It's not like you can write a magic parser and then suddenly arbitrary programs get completion support.

Hi @chrisant996 ,
Understood. What I meant to say is the go , rustup and cargo help text format is same as requested in chrisant996/clink-gizmos#11. So, we may write some common help parser to handle such programs , definitely it is much complex compared to what current auto_argmatcher can do.
