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-44955

Start with the roachtest README and the TeamCity artifacts linked in the report, especially the full command output and retained SSH log under disk-stalled/wal-failover/among-stores. Compare the related ssh_problem failures listed across branches and the roachdash history; done means identifying and addressing the recurring failure pattern, with the affected roachtest no longer producing this flake.
