History
Aleksandr Bykov 8afdae24d2 test: fix flaky test_kill_coordinator_during_op 
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
