Botond Dénes 70261dc674 Merge 'test/cluster: scale failure_detector_timeout_in_ms by build mode' from Marcin Maliszkiewicz ...

The failure_detector_timeout_in_ms override of 2000ms in 6 cluster test files is too aggressive for debug/sanitize builds. During node joins, the coordinator's failure detector times out on RPC pings to the joining node while it is still applying schema snapshots, marks it DOWN, and bans it — causing flaky test failures.

Scale the timeout by MODES_TIMEOUT_FACTOR (3x for debug/sanitize, 2x for dev, 1x for release) via a shared failure_detector_timeout fixture in conftest.py.

Fixes https://scylladb.atlassian.net/browse/SCYLLADB-1587
Backport: no, elasticsearch analyser shows only a single failure

Closes scylladb/scylladb#29522
