Looks like there is a bit of an issue in the Bluderbuss (Prow plugin)
where it prefers to pick reviewers from a parent OWNERS files,
instead of using an approver from a current OWNERS file as
an additional reviewer.
Updates kubeadm version resolution to use kubernetes community infra
bucket to fetch appropriate k8s ci versions. The images are already
being pulled from the kubernetes community infra bucket meaning that a
mismatch can occur when the ci version is fetched from the google infra
bucket and the image is not yet present on k8s infra.

Originally raised as an issue with invalid versions to plan, but it has
been determined with air gapped environments and development versions it
is not possible to fully address that issue.
But one thing that was identified was that we can do a better job in how
we output the upgrade plan information. Kubeadm outputs the requested
version as "Latest stable version", though that may not actually be the
case. For this instance, we want to change this to "Target version" to
be a little more accurate.
Then in the component upgrade table that is emitted, the last column of
AVAILABLE isn't quite right either. Also changing this to TARGET to
reflect that this is the version we are targetting to upgrade to,
regardless of its availability.
There could be some improvements in checking available versions,
particularly in air gapped environments, to make sure we actually have
access to the requested version. But this at least clarifies some of the
output a bit.

Add DefaultedStaticInitConfiguration() which can be
used instead of DefaultedInitConfiguration() during unit tests.
The later can be slow since it performs dynamic defaulting.
Apply the label:
"node.kubernetes.io/exclude-from-external-load-balancers"
To control plane nodes to preserve backwards compatibility
with the legacy mode where "master" nodes were excluded from
LBs.
During upgrade the coredns migration library seems to require
that the input version doesn't have the "v" prefix".
Fixes a bug where the user cannot run commands such as
"kubeadm upgrade plan" if they have `v1.8.0` installed.
Assuming this is caused by the fact that previously the image didn't
have a "v" prefix.
Fixes an issue where some kubeadm phases fail if a certificate file
contains a certificate chain with one or more intermediate CA
certificates. The validation algorithm has been changed from requiring
that a certificate was signed directly by the root CA to requiring that
there is a valid certificate chain back to the root CA.
