refactor: use object cache instead of event info

loft-sh / vcluster

vCluster - Create fully functional virtual Kubernetes clusters - Each vcluster runs inside a namespace of the underlying k8s cluster. It's cheaper than creating separate full-blown clusters and it offers better multi-tenancy and isolation than regular namespaces.

Introduces an optional object cache syncers can use to save the before state of objects, which helps to determine what exactly has changed on the other side
Moves the patch & apply from vCluster pro into oss
Refactors all syncers that were using the "old" bidirectional syncing approach to use the new one
