MarshalClusterConfigurationToBytes has capabilities to output the component
configs, as separate YAML documents, besides the kubeadm ClusterConfiguration
kind. This is no longer necessary for the following reasons:
- All current use cases of this function require only the ClusterConfiguration.
- It will output component configs only if they are not the default ones. This
can produce undeterministic output and, thus, cause potential problems.
- There are only hacky ways to dump the ClusterConfiguration only (without the
component configs).
Hence, we simplify things by replacing the function with direct calls to the
underlaying MarshalToYamlForCodecs. Thus marshalling only ClusterConfiguration,
when needed.

Stop using //pkg/util/normalizer. Use local versions of LongDesc and Examples,
that do not require any external dependencies (other than the Go standard
library).

one test also proved it did not call the internet
but this was not fool proof as it did not return a string
and thus could be called with something expecting to fail.
updated the network calls to be package local so tests could pass their
own implementation. A public interface was not provided as it would not
be likely this would ever be needed or wanted.
When a kubeconfig file is read from disk it may lack the
propper mapping between contexts and clusters.
In such a case the kubeconfig phase backend will panic,
without throwing a sensible error.
Add nil checks for a couple of map operations in
validateKubeConfig().
add startup sequence duration and readyz endpoint
add rbac bootstrapping policy for readyz
add integration test around grace period and readyz
rename startup sequence duration flag
copy health checks to fields
rename health-check installed boolean, refactor clock injection logic
cleanup clock injection code
remove todo about poststarthook url registration from healthz
- Added scripts for update and verify
- golang AST code for scanning and fixing imports
- default regex allows it to run on just test/e2e.* file paths
- exclude verify-import-aliases.sh from running in CI jobs

This patch refactors pkg/util/mount to be more usable outside of
Kubernetes. This is done by refactoring mount.Interface to only contain
methods that are not K8s specific. Methods that are not relevant to
basic mount activities but still have OS-specific implementations are
now found in a mount.HostUtils interface.
This helper is used in tests and pulls in unnecessary dependency, which should
not be used if kubeadm is to move to staging.
Replace with direct use of the GroupResource type.

ValidateDNS1123Subdomain is a simple wrapper around IsDNS1123Subdomain, however
it's the only reason for us to pull k8s.io/kubernetes/pkg/apis/core/validation
as a dependency.
To avoid unnecessary dependencies, replace the use of ValidateDNS1123Subdomain
with IsDNS1123Subdomain.

RBAC construction helpers are part of the Kubernetes internal APIs. As such,
we cannot use them once we move to staging.
Hence, replace their use with manual RBAC rule construction.

During the control plane joins, sometimes the control plane returns an
expected error when trying to download the `kubeadm-config` ConfigMap.
This is a workaround for this issue until the root cause is completely
identified and fixed.
Ideally, this commit should be reverted in the near future.
