Distributed datastore solution for Module Sync Watchdog
- use semaphore map in ModuleSyncWatchdog - increase test timeout, because it needs more time for hazelcast initialization Issue-ID: CPS-1015 Change-Id: I71feed8fbbd047af9fabba29a5f762a1f17a1c78 Signed-off-by: kissand <andras.zoltan.kiss@est.tech>
