> Distributed sync non-tx cache.
> Situation:
> 1) A node is joining the cluster, requesting some segment
> 2) RemoveCommand is sent to backup owner with ignorePreviousValue=true
> 3) It looks up the entry and finds null
> 4) State transfer invokes the PutKeyValueCommand and sets the value for removed entry (updateKeys has not the key yet)
> 5) RemoveCommand adds its key to updateKeys set, but it does not remove the value as it is already null (in its context)
> Result: the value is removed on primary but on backup this is still present
