Ayush KumarandGitHub 0a599ad177 Refactor: Pre-Validation Hooks to be More Extensible and Testable (#6978)
* refactor: pre-start hook implementation

- Introduced a new `hook.go` file defining the `PreStartHook` interface for pre-start validation hooks.
- Removed the old `pre_start_hook.go` file which contained the `SystemCRDValidationHook` implementation.
- Updated the server initialization code to use the new hook structure, specifically integrating the `crdvalidation` package for pre-start validation.
- Enhanced logging for pre-start hook execution to improve clarity on hook names and execution results.
