## What changes were proposed in this pull request? Currently we use two different Concurrent collections, ConcurrentMap to keep entries in the cache and ConcurrentSet to keep track for the entries which can be closed. Usage of these two are causing [deadlock](https://issues.apache.org/jira/browse/HDDS-9871) and [race condition](https://issues.apache.org/jira/browse/HDDS-10076) problem. In this change, usage of ConcurrentSet to keep track of closable entries is removed. Now we are iteration over the ConcurrentMap itself and checking if entry's reference size has reached zero and can be closed. If it has, we close the RocksDB object and remove the entry from the SnapshotCache. ## What is the link to the Apache JIRA [HDDS-10103](https://issues.apache.org/jira/browse/HDDS-10103) ## How was this patch tested?
