Improve error returned when fetching container logs during pod termination

**What this PR does / why we need it**:

This change better handles fetching of logs when a container is in a crash loop backoff state. In cases where it is unable to fetch the logs, it gives a helpful error message back to a user who has requested logs of a container from a terminated pod. Rather than attempting to get logs for a container using an empty container ID, it returns a useful error message.

In cases where the container runtime gets an error, log the error but don't leak it back through the API to the user.


**Which issue(s) this PR fixes**:
Fixes #59296
