Custom Completions in Go

[darthShadow]

What is your current rclone version (output from rclone version)?

N/A

What problem are you are trying to solve?

Custom Completions defined in Go to make it work for both Bash & Zsh (and any other shells supported by cobra).

How do you think rclone should be changed to solve that?

Cobra has recently added support for custom completions in go instead of directly in bash or zsh and these completions are automatically translated for all the shells supported. Once we have migrated the custom completion from bash to go, then zsh remote completions should also start working.

spf13/cobra#1070 - ZSH Support for the above - Included in the latest master branch

That is very neat - well spotted - and would certainly be easier for to maintain with the completions in Go.

I found the docs here: https://github.com/spf13/cobra/blob/master/shell_completions.md

@sgtpep did the original bash completion script for which I am truly grateful as I'm a mediocre bash programmer at best!

Do you want to work on this @darthShadow ? Or maybe @sgtpep ?

I have almost zero knowledge about writing/reading bash or zsh functions so hopefully, @sgtpep or someone else with more experience in that aspect can do the conversion.
