-------------------------------------------------------------------

the bug is in the following scenario:
1) near node requests key, save it in near cache
2) near node becames primary or backup
3) new value is inserted and propagated to the node. On this step, new value is set into DHT cache, not Near one. We have obsolete value in Near cache
4) near node again became near
5) we have obsolete value in Near cache. This is a bug 

Fix is to remove value from near cache on 3 step. Removing should be performed in
processDhtAtomicUpdateRequest(), after new value is inserted in DHT cache.
