upgrade spf13/cobra from v1.0.0 to v1.1.1 will probably have side-effects and tests failing, ie:

'make test' suddently starting to report issues, like:

--- FAIL: TestGenerateDocs (0.02s)
    --- FAIL: TestGenerateDocs/pause (0.00s)
        generate-docs_test.go:47: Docs are not updated. Please run `make generate-docs` to update commands documentation:   strings.Join({
              	... // 9 identical lines
              	"pause Kubernetes",
              	"",
            + 	"### Synopsis",
            + 	"",
            + 	"pause Kubernetes",
            + 	"",
              	"```",
              	"minikube pause [flags]",
              	... // 30 identical lines
              }, "\n")
    --- FAIL: TestGenerateDocs/unpause (0.01s)
        generate-docs_test.go:47: Docs are not updated. Please run `make generate-docs` to update commands documentation:   strings.Join({
              	... // 9 identical lines
              	"unpause Kubernetes",
              	"",
            + 	"### Synopsis",
            + 	"",
            + 	"unpause Kubernetes",
            + 	"",
              	"```",

              	... // 30 identical lines
              }, "\n")

It contains the fix for macOS 11

Need a patch for the broken kubernetes sha256 checksums,
version 1.19.3 and matching older don't have newlines...

- skip, if sudo needs a password
- improve temp files processing
- do not preload

polls GitHub for the current Kubernetes Stable release and latest RC or Beta pre-release, then automatically updates local repo and/or creates a unique PR in kubernetes/minikube repo

* force dependency for release purposes

* revert original idea and add loads of debugging

* hey more debugging cool

* fix debugging

* drilling down debugging

* revert to original solution

* fix comment

update_kubernetes_version: implement a standalone program that polls GitHub for the latest Kubernetes release

$ sed -i 's/miniube start/minikube start/g' $(git grep -l 'miniube start')
