The new flag will parse the `--reserved-memory` flag straight forward
to the []kubeletconfig.MemoryReservation variable instead of parsing
it to the middle map representation.
It gives us possibility to get rid of a lot of unneeded code and use the single
presentation for the reserved-memory.

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.
Follow-up to kubernetes/kubernetes#97087

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.

we disabled the /healthz check because our test blocks one post-start
hook from finishing. Instead we should check all the other /healthz/...
endpoints before running the tests
Add DefaultedStaticInitConfiguration() which can be
used instead of DefaultedInitConfiguration() during unit tests.
The later can be slow since it performs dynamic defaulting.
This commit replaces the CSIMigrationXXXComplete flag
with InTreePluginXXUnregister flag. This new flag will
be a superset of the CSIMigrationXXXComplete. But this
decouple the plugin unregister from CSI migration. So
if a K8s distribution want to go directly with CSI and
do not support in-tree, they can use this flag directly.
Testing:
1. Enable the InTreePluginXXUnregister and not CSIMigrationXXX,
verify that the PVC using old plugin name will have error
saying cannot find the plugin
2. Enable both the InTreePluginXXUnregister and CSIMigrationXXX
verify that the PVC using old plugin name will start to use
the migrated CSI plugin
Migrate how resource lock and leader election config is generated to new way, hidding kubeClient. This also halfs kubeClient timeout, making it an useful value.
If timeout is equal to RenewDeadline and we hit client timeout on request, there will be no retry, as RenewDeadline part will cancel the context and lose leader election. So setting a timeout to value at least equal to RenewDeadline is pointless.
Setting it as half of RenewDeadline is a heuristic to resolve this missing retry problem without adding additional parameter.
