Introduce a way to specify template or workflow during machine deletion #463
Description
Description
Currently, CAPT (Cluster API Provider Tinkerbell) has the ability to create a default template during machine provisioning to boot into the actual OS. However, during machine deletion, there's no mechanism for users to specify custom cleanup workflows.
Problem Statement
When deleting machines, users often need to perform hardware-specific cleanup operations before powering off the machine, such as:
- Wiping disks to ensure data security
- Cleaning up EFI boot entries
- Resetting hardware configurations
- Running vendor-specific cleanup actions
Proposed Solution
Introduce a new field in the TinkerbellMachineTemplate CRD that allows users to specify a template to be executed during machine deletion.
