k3s fish completion

[RafalSkolasinski]

Is your feature request related to a problem? Please describe.

I am using fish shell and would like to have shell completion for k3s.

Describe the solution you'd like

The

k3s completion fish

produces valid fish completions.

Describe alternatives you've considered

None.

Additional context

K3s only provides completion for bash and zsh. It'd be great if we could extend that to include also fish completions

$ k3s completion --help
NAME:
   k3s completion - Install shell completion script

USAGE:
   k3s completion [SHELL] (valid shells: bash, zsh)

OPTIONS:
   -i  Install source line to rc file

Also it seems that the issue is solved for k3d: https://k3d.io/v5.3.0/usage/commands/k3d_completion/

K3s uses urfave cli as the CLI library. This library has builtin support to generate bash and zsh completion code. It unfortunately does not support fish, which makes it unlikely that we will be able to add fish autocompletion to K3s. K3d uses cobra as its CLI library, which does have native fish support.

Closing as we don't have any current plans to change our CLI library.
