`test_crashed_node_substitution` intermittently failed: ```python assert len(gossiper_eps) == (len(server_eps) + 1) ``` The test crashed the node right after a single ACK2 handshake (`finished do_send_ack2_msg`), assuming the node state was visible to all peers. However, since gossip is eventually consistent, the update may not have propagated yet, so some nodes did not see the failed node. This change: Wait until the gossiper state is visible on peers before continuing the test and asserting. Fixes: [SCYLLADB-1256](https://scylladb.atlassian.net/browse/SCYLLADB-1256). backport: this issue may affect CI for all branches, so should be backported to all versions.

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.
