Migrate backup sync controller from code-generator to kubebuilder (#5218)
* Migrate backup sync controller from code-generator to kubebuilder 1. use kubebuilder's reconcile logic to replace controller's old logic. 2. use ginkgo and gomega to replace testing. 3. modify BSL reconciler registration method. Signed-off-by: Xun Jiang <blackpiglet@gmail.com> * Add Option for PeriodicalEnqueueSource.
