WHAT
This PR includes a lifecycle hook (PreStop) method to handle node draining and termination events.
WHY
The primary goal of this PR is to implement a lifecycle hook (Hook interface) for handling Kubernetes node draining events, particularly in the PreStop lifecycle stage. The need arises from the requirement to ensure that VolumeAttachments associated with a node are properly cleaned up before the node is fully drained or shut down.
FYI
This PR implements a package that primarily handles hook processing. Once this PR is merged, the next step will be to update
main.go
and themanifest
to incorporate this functionality by adding the PreStop lifecycle event handling.
