Rerun init containers when the pod needs to be restarted
Whenever pod sandbox needs to be recreated, all containers associated
with it will be killed by kubelet. This change ensures that the init
containers will be rerun in such cases.
The change also refactors the compute logic so that the control flow of
init containers act is more aligned with the regular containers. Unit
tests are added to verify the logic.
This fixes#36485
