selfLink is deprecated in newer versions of k8s

[fedreg-bn]

Thanks for this package! Was looking for something similar and stumbled across this.

Are you still maintaining it?

I hit an issue where I got a JSON readtable error when trying to get pods info.

It's because of metadata.selfLink being deprecated since k8s v1.20 so this line (selflink (kubectl--run (format "get deployment.apps %s -o jsonpath={.metadata.selfLink}" name))) returns something like "resource not found" that blows up the json read.

I can comment that out and set the selector to "" to get around it, but then of course it doesn't filter correctly and returns all the pods in the namespace.

(defun kubectl-open-deployment (name)
  (let* ((selflink (kubectl--run (format "get deployment.apps %s -o jsonpath={.metadata.selfLink}" name)))
         (json-object-type 'hash-table)
         (json-array-type 'list)
         (json-key-type 'string)
	 ;; (scale (json-read-from-string (kubectl--run (format "get --raw %s/scale" selflink))))
	 
	 (selector "") ;(gethash "selector" (gethash "status" scale)))
	 (ns kubectl--namespace)
	 (ctx kubectl--context))
    (switch-to-buffer "*kubernetes*")
    (tabulated-list-mode)
    (kubectl-pods-mode)
    (setq kubectl--pods-selector selector)
    (setq kubectl--namespace ns)
    (setq kubectl--context ctx)
    (kubectl-pods-refresh))) 

my kubectl knowledge is limited but I assume everything will work if the selector is set directly?

I can take a stab at a PR at some point but it might be a bit.. wanted to check in about it first.

thanks again!
