169604d906 Validate single-stack --nodeport-addresses sooner 
In the dual-stack case, iptables.NewDualStackProxier and
ipvs.NewDualStackProxier filtered the nodeport addresses values by IP
family before creating the single-stack proxiers. But in the
single-stack case, the kube-proxy startup code just passed the value
to the single-stack proxiers without validation, so they had to
re-check it themselves. Fix that.

e7ed7220eb Explicitly pass IP family to proxier 
Rather than re-determining it from the iptables object in both proxies.

fb84c4f0f0 Fix kube-proxy dual-stack-iptables-binary-presence check 
Kube-proxy was checking that iptables supports both IPv4 and IPv6 and
falling back to single-stack if not. But it always fell back to the
primary IP family, regardless of which family iptables supported...
Fix it so that if the primary IP family isn't supported then it bails
out entirely.

fd60b9c492 kubeadm: return the output from stdout and stderr 
It was just saying the copy of file failed with `exit status 1`,
no much details for what's going wrong.

Combine the stderr and stdout and show those info will be easier
for us to fix the problem.

f8da9ab287 kubeadm: return stored FakedServerVersion when dry-running 
If we are dry-running, do not attempt to fetch the /version
resource and just return the stored FakeServerVersion,
which is done when constructing the dry-run client in
upgrade/common.go#getClient().

The problem here is that during upgrade
dry-run client reactors are backed by a dynamic client
via NewClientBackedDryRunGetterFromKubeconfig() and
for GetActions there seems to be no analog to
Discovery().Serverversion() resource for a dynamic client(?).

54b73deaca kubeadm: handle dry run GET actions from fake discovery 
The kubeadm dry run client reactor code is flawed as it assumes
all invoked "get" verb actions can be casted to GetAction.
Apparently that is not the case when Discovery().ServerVersion()
and other discovery calls are made. In such cases the action
type is the bare ActionImpl.

Catch if an action can be casted to ActionImpl and construct a
GetAction from it. GetActionImpl only suppersets ActionImpl with
a Name field (empty string in this case).

Add unit test for Discovery().ServerVersion().

b0f38b223e kubeadm: revert feature to backup kubelet config for "upgrade node" 
There seems to be a bug where it's not possible to write to
/etc/kubernetes/tmp... at the time of backing up the old kubelet
config.yaml

Also this kubelet config backup only targets "upgrade node"
and it should also target "upgrade apply".

Revert the related changes until a fully working feature
is implemented.
