-###  BeforeControlPlaneUpgrade
-
-This hook is called before a new version is propagated to the control plane object. Runtime Extension implementers
-can use this hook to execute pre-upgrade add-on tasks and block upgrades of the ControlPlane.

-Note: 
-- When an upgrade is starting, BeforeControlPlaneUpgrade will be called after BeforeClusterUpgrade is completed.
-- When an upgrade is in progress BeforeControlPlaneUpgrade will be called for each intermediate version that will
-  be applied to the control plane (instead BeforeClusterUpgrade will be called only once at the beginning of the upgrade).
