Ilya Shishkov updated IGNITE-19239:
-----------------------------------
    Description: 
There are possible error messages about checkpoint read lock acquisition 
timeouts and critical threads blocking during snapshot restore process (just 
after caches start).

How to reproduce: 
# Set checkpoint frequency less than failure detection timeout.
# Ensure, that cache groups partitions states restoring lasts more than failure 
detection timeout, i.e. it is actual to sufficiently large caches.

Reproducer:  [^BlockingThreadsOnSnapshotRestoreReproducerTest.patch]
