Removing update/patch methods from UpdateControl

[csviri]

For v6 we should consider removing the methods from UpdateControl like patchStatus , patchResource etc.

The reason is that it could be rather confusing how those methods exactly do in the background, since we have flags to control their behavior - if they should use Server Side Apply or not for example.

Users can use the directly the Kubernetes client and/or utilities like PrimaryUpdateAndCacheUtils.

We might want to also rename UpdateControl to ReconcileControl.
