[pve-devel] [PATCH common] Fix 1891: Add zsh tab completion script generator

[Christian Ebner]

Add zsh tab completion generator function to automatically generate the
zsh scripts used for autocompletion.
This uses the older zsh completion system relying on compctl to call the
executables analogos to the bash completer.
