Previously, we had some false positives from the
sqlsmith
roachtestfiled because of "inbox communication errors" which were actually
triggered because of the vectorized panic injection. These errors
usually mean that a node died, so we used the errors as a proxy for the
crash. This commit adjusts the test to instead ping all nodes in the
cluster to see whether they are up or not and not rely on the
communication errors. This allows us to ignore the false positives
because of the panic injection.
Fixes: #66174.
Release note: None
