Ivan Rakov updated IGNITE-6016:
-------------------------------
    Description: 
We check topologyHash in ackTopology in order to avoid printing "Topology 
snapshot" message twice. It's redundant - we can just atomically increase 
topology version with GridAtomicLong#setIfGreater.
It's the only usage of topology hash in Ignite, so we should remove it with all 
related tests.
