roachtest: ssh_problem failed

**Note:** This build has runtime assertions enabled. If the same failure was hit in a run without assertions enabled, there should be a similar failure without this message. If there isn't one, then this failure is likely due to an assertion violation or (assertion) timeout.

Jira issue: CRDB-52576

Start with pkg/cmd/roachtest/README.md and the failure at test_runner.go:823. Review the linked TeamCity build, artifacts, and Grafana data to trace the ssh_problem during cluster.PutE. Done means identifying the cause and verifying that the affected roachtest no longer fails with this SSH error.
