include zsh completion

Well we got bash. That is awesome. We might want to think about zsh.

FYI kubectl handles this by wrapping the bash completion script and running sed to clean up things.

An important exceprt:

__kubectl_convert_bash_to_zsh() {
	sed \
	-e 's/declare -F/whence -w/' \
	-e 's/local \([a-zA-Z0-9_]*\)=/local \1; \1=/' \
	-e 's/flags+=("\(--.*\)=")/flags+=("\1"); two_word_flags+=("\1")/' \
	-e 's/must_have_one_flag+=("\(--.*\)=")/must_have_one_flag+=("\1")/' \
	-e "s/${LWORD}_filedir${RWORD}/__kubectl_filedir/g" \
	-e "s/${LWORD}_get_comp_words_by_ref${RWORD}/__kubectl_get_comp_words_by_ref/g" \
	-e "s/${LWORD}__ltrim_colon_completions${RWORD}/__kubectl_ltrim_colon_completions/g" \
	-e "s/${LWORD}compgen${RWORD}/__kubectl_compgen/g" \
	-e "s/${LWORD}compopt${RWORD}/__kubectl_compopt/g" \
	-e "s/${LWORD}declare${RWORD}/__kubectl_declare/g" \
	-e "s/\\\$(type${RWORD}/\$(__kubectl_type/g" \
	<<'BASH_COMPLETION_EOF'
`
	out.Write([]byte(zsh_initialization))

	buf := new(bytes.Buffer)
	kubectl.GenBashCompletion(buf)
	out.Write(buf.Bytes())

	zsh_tail := `
BASH_COMPLETION_EOF
}

Maybe we could do the same here? I haven't tried it myself.

There is already code in kubectl for this, we would just need to appropriate said code :)
