In SCYLLADB-2058 we observed a timeout exception while querying the base table after restarting nodes 2 and 3. Unfortunately, logs don't give us much useful information about the root cause. This patch adds basic checks that nodes see each other after the restart and that the cql connection sees restarted node. It doesn't guarantee that the error won't occur again - in logs from SCYLLADB-2058 we see that each node sees other via gossip after part of the cluster is restarted. In case the error will occur again, this commit also increases logging level of `cql_server` and `storage_proxy`. Refs SCYLLADB-2058 Closes scylladb/scylladb#29951

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
