Merge pull request #23797 from sttts/sttts-zsh-completion
Automatic merge from submit-queue Add zsh completion for kubectl This is based on the zsh emulation of the bash completion system (compare `bashcompinit` at http://zsh.sourceforge.net/Doc/Release/Completion-System.html). Because this emulation is not 100% complete, a number of functions are added or extended to work with the bash completion of kubectl.
