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.

Tests for scaling down based on external metric are flaky. I think this
is because they:
- Start with 2 replicas,
- Export metric value == 1/2 target,
- Expect scale down to 1.
Since the expected recommendation is exactly 1 it might flake (and with
scale down stabilization any recommendations higher than 1 will
persist).
Change expected value of the metric so recommended size will be lower
than 1. This should make those tests less flaky.
In v1alpha3's, control plane component config options were nested directly into
the ClusterConfiguration structure. This is cluttering the config structure and
makes it hard to maintain. Therefore the control plane config options must be
separated into different substructures in order to graduate the format to beta.
This change does the following:
- Introduces a new structure called ControlPlaneComponent, that contains fields
common to all control plane component types. These are currently extra args
and extra volumes.
- Introduce a new structure called APIServer that contains
ControlPlaneComponent and APIServerCertSANs field (from ClusterConfiguration)
- Replace all API Server, Scheduler and Controller Manager options in
ClusterConfiguration with APIServer, ControllerManager and Scheduler fields
of APIServer and ControlPlaneComponent types.

One can run:
make generated_files UPDATE_API_KNOWN_VIOLATIONS=true
to update the checked-in known API violation exceptions list.
Also updated README and the error message on how to resolve the
failure.
