Currently, there are some unit tests that are failing on Windows due to
various reasons:
- filepath.IsAbs does not consider "/" or "\" as absolute paths, even
though files can be addressed as such.
- paths not properly joined (filepath.Join should be used).
- files not closed, which means that they cannot be removed / renamed.
- some assertions fail due to slashes / backslashes not matching.
- backslashes need to be escaped in yaml files, or put between ''
instead of "".
These are based on recommendation from
[staticcheck](http://staticcheck.io/).
- Remove unused struct fields
- Remove unused function
- Remove unused variables
- Remove unused constants.
- Miscellaneous cleanups
Used T.Run API for kubeadm tests in app/phases/*
This should improve testing output and make it more visible
which test is doing what.

For historical reasons InitConfiguration is used almost everywhere in kubeadm
as a carrier of various configuration components such as ClusterConfiguration,
local API server endpoint, node registration settings, etc.
Since v1alpha2, InitConfiguration is meant to be used solely as a way to supply
the kubeadm init configuration from a config file. Its usage outside of this
context is caused by technical dept, it's clunky and requires hacks to fetch a
working InitConfiguration from the cluster (as it's not stored in the config
map in its entirety).
This change is a small step towards removing all unnecessary usages of
InitConfiguration. It reduces its usage by replacing it in some places with
some of the following:
- ClusterConfiguration only.
- APIEndpoint (as local API server endpoint).
- NodeRegistrationOptions only.
- Some combinations of the above types, or if single fields from them are used,
only those field.

Writable was added to HostPathMount in v1alpha1 in order to control if an extra
volume is mounted in read only or writable mode.
Usually, in Kubernetes, this option is referred to as ReadOnly, instead of
Writable and is defaulted to `false`. However, at the time, all extra volumes
to pods were defaulted to read-only. Therefore, to avoid changes to existing
v1alpha1 configs, this option had to be added with reversed meaning.
Hence, it's called `writable`.
Now, with the migration towards v1beta1, we can safely change this to ReadOnly
and get it in sync with the reset of Kubernetes.

This is required for a working CA root, as /etc/ssl/certs on a few
Linux distributions just contains a bunch of symlinks.
Container Linux and Debian have symlinks pointing to
/usr/share/ca-certificates, ArchLinux has symlinks pointing
to /etc/ca-certificates.
On Debian /etc/ssl/certs can also include symlinks pointing
to /usr/local/share/ca-certificates for local CA certificates.
Fix: kubeadm/#671
Audit logs are configurable via the MasterConfiguration file.
All options are ignored unless the FeatureGate is enabled.

We have a way to specify the cloudProvider in kubeadm.conf. We also
add `--cloud-config /etc/kubernetes/cloud-config` to both the
kubernetes api server and controller manager yaml files if one exists
on the box. However we fail to make that file available to the
process running in the container. We need to make this `cloud-config`
file available to both processes similar to how controller-manager.conf
is passed to controller manager.
What this PR does / why we need it:
when the flexvolumeDirVolumePath is truely existent in the host,
```cmd/kubeadm/app/phases/controlplane``` unit tests will be failed.
Fixes#56189
Release note:
```release-note
NONE
```
If certificates for etcd are located in the same directory or
subdirectories of kubernetes pki directory, don't create separate
volumes and mounts in manifests.

Controller manager needs access to Flexvolume plugin when
using attach-detach controller interface.
This PR adds the host mount path for the default directory of flexvolume
plugins
