[Test Fix] Fake docker client can remove containers which have not been started

**What this PR does / why we need it**:
During kubemark-5000 scalability tests, which use the fake docker client, we encountered a bug where containers where the pod was deleted before the container was started could not be deleted.
This is because we only remove pods from the `ExitedContainers` list.  Containers are only added to this when they have been created, started, and then stopped.  However, containers that have only been created, but not started cannot be deleted.  This PR fixes this issue by allowing containers with `State.Running=false` to be deleted.

**Which issue(s) this PR fixes**:
Ref #53327
