Subject: [PATCH] polishing

This commit adds an explicit error message when the BackOff instance
has returned BackOffExecution#STOP which basically means that no
further attempts are allowed.

This error message is a convenience way to notify that the container is
about to be shut down.

Issue: SPR-11746
