 A Pod can restart, causing re-execution of init containers, for the following
 reasons:

-  Any changes to the init container image restarts the Pod. App container image

 * The Pod infrastructure container is restarted. This is uncommon and would
   have to be done by someone with root access to nodes.
 * All containers in a Pod are terminated while `restartPolicy` is set to Always,
   forcing a restart, and the init container completion record has been lost due
   to garbage collection.
