SQLancer: Server restarts during evaluating workload

[qvad]

Jira Link: DB-1015
At some moment of running test cluster became temporary unavailable and all testing queries are dropped for various reasons
Unfortunately I can't provide clear scenario right now, because straight reproduce doesn't work

I've found following FATAL stack trace in server logs
