## What changes were proposed in this pull request? There is a deadlock between checkpointing creation for Bootstrapping and RocksDBCheckpointDiffer#pruneSstFiles. Bootstrapping takes the BootstrapStateHandler#lock before checkpointing creation and then takes lock on RocksDBCheckpointDiffer instance to unpause the compaction thread/s. On the other hand RocksDBCheckpointDiffer#pruneSstFiles is synchronized function which first takes lock on RocksDBCheckpointDiffer instance and takes BootstrapStateHandler#lock before removing any files. Hence both threads, checkpointing creation for Bootstrapping and pruneSstFiles background task, are blocking each other. In this change, synchronized block to notify RocksDBCheckpointDiffer to unpause the compaction has been removed. Now heckpointing creation for Bootstrapping and pruneSstFiles background threads won't block each other. ## What is the link to the Apache JIRA HDDS-9486 ## How was this patch tested?
