> TTL expire times for entries are stored in PendingEntriesTree, which is 
> singleton for cache. When expiration occurs, all system threads iterate 
> through the tree in order to remove expired entries. Iterating through single 
> tree causes contention and perfomance loss. 
> Related performance issue: https://issues.apache.org/jira/browse/IGNITE-5793
> We should keep instance of PendingEntriesTree for each partition, like we do 
> for CacheDataTree.
