@rosti thanks for this PR!
I have no strong opinion on the usage of a shared struct vs dedicated struct.
Everything else seems ok
Only one question. The Change about HostPathMount.Writable to ReadOnly is going to be addressed in another PR?

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.
