Add support for kubelet HTTP endpoints

[Yuval Avrahami]

The kubelet readonly server (normally at :10255) listens for HTTP. The kubelet main server (normally at :10250) will also listen for HTTP when no TLS configuration is specified.
When attempting to issue commands through kubeletctl to a kubelet's HTTP endpoint, the following error occurs:

$ kubeletctl --server 127.0.0.1 --port 10255 pods
[*] Failed to run HTTP request with error: Get https://127.0.0.1:10255/pods: http: server gave HTTP response to HTTPS client

$ curl http://127.0.0.1:10255/pods # works
{"kind":"PodList","apiVersion":"v1", ... }

Consider adding support for HTTP, perhaps through a cmdline flag.

Also, great tool (:

Hi @yuvalavra, thanks for the feedback! :)

I did some changes and added new flag --http and support on any port, it seems to work on my side, I will appreciate if you can check it again and let me know if it works on your side too.

By the way, the default IP is 127.0.0.1 so you don't need to use -s, you can use it like that:

kubeletctl --http --port 10255 pods

I uploaded a new version v1.2:

curl -LO https://github.com/cyberark/kubeletctl/releases/download/v1.2/kubeletctl_linux_amd64 && chmod a+x ./kubeletctl_linux_amd64 && mv ./kubeletctl_linux_amd64 /usr/local/bin/kubeletctl

Thanks for the quick response, works on my side
