The test hardcoded the expected number of coordinator elections (2, 3, 4, 5) for each phase. If a prior phase triggered an extra election, subsequent phases would wait for a count that was already reached or would never match. Fix by reading the current election count before each operation and expecting exactly one more, making each phase independent of prior history. Also add wait_for_no_pending_topology_transition() calls after each coordinator election to ensure the topology state machine has fully settled before proceeding with restarts and further operations. Decrease the failure detector timeout (failure_detector_timeout_in_ms) to 2000 ms on all test nodes so that coordinator crashes are detected faster, reducing test wallclock time and timeout-related flakiness. Enable raft_topology=trace logging on all test nodes to aid post-failure diagnosis. Add diagnostic logging in wait_new_coordinator_elected(). Fixes: SCYLLADB-1089 Closes scylladb/scylladb#29284

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.
