Ivan Pavlukhin updated IGNITE-9404:
-----------------------------------
    Description: This case fires very rarely in 
{{TcpDiscoveryRestartTest.testRestart}}. Caches with {{SYNC}} rebalance mode 
are affected. When _starting_ instance is trying to preload partitions for such 
cache from another instance which _stops_ around the same time, first instance 
could hang infinitely. When {{SYNC}} rebalance mode is enabled starting 
instance awaits on _preload future_ in start routine. In another thread it 
starts fetching partitions and receives an error from _stopping_ instance and 
cancels _rebalance future_ but _preload future_ is not cancelled.  (was: This
