Under certain circumstances, specially when using an insecure external
etcd cluster (no certificates), or when using external certificates (
no CA key), some keys inside the kubeadm-certs secret data can contain
the key with an empty value on the map.
When downloading certs just ignore those that are blank and inform the
user about it.
The fuzzer test for NodeRegistrationOptions is defaulting the CRISocket member.
This is a left over from the times this member was statically defaulted in the
config. Now that the member is dynamically defaulted, setting CRISocket to foo
can cause issues to get undetected by the fuzzer test with this member.
The resolution is to stop setting CRISocket in the fuzzer test.

The standalone execution of upload-certs phase does not print
the key that that user should use for the newly uploaded encrypted
secret. Print this key in the upload-certs phase in both
standalone mode or if executed in the standard init workflow.
Make it possible to omit the printing if the user passes
--skip-certificate-key-print.
Also:
- Uppercase string in Printf call in copycerts.go
- Don't use V(1) for the "Skipping phase" message in uploadcerts.go
instead always print a message that the user case use
--experimental-upload-certs. This solves a problem if the user tried
the standalone phase but didn't pass --experimental-upload-certs.
Add ResetClusterStatusForNode() that clears a certain
control-plane node's APIEndpoint from the ClusterStatus
key in the kubeadm ConfigMap on "kubeadm reset".
Hardcoding a temp path of /tmp/... is not portable and can potentially cause
other issues (such as flakyness) too.
Use TempFile instead.

Certain join phases have flags that are redundant:
- getControlPlanePreparePhaseFlags():
- amend flags (use switch / case)
- add example for the parent command
- rename internal function and sub-phase "manifests"
to "control-plane"
- getControlPlaneJoinPhaseFlags():
- amend flags
- remove MacroCommandLongDescription
- move most unrelated to phases output to klog.V(1)
- rename some prefixes for consistency - e.g.
[kubelet] -> [kubelet-start]
- control-plane-prepare: print details for each generated CP
component manifest.
- uppercase the info text for all "[reset].." lines
- modify the text for one line in reset
Add an extra flag isSecondaryControlPlane to RunInitNodeChecks
which can be used to indicate that the node we are checking is
a secondary control-plane. In such a case we skip some tests
that are already covered by RunJoinNodeChecks and
RunOptionalJoinNodeChecks.
