…pecified number of threads instead of only single threaded. (apache#1933) ### What is the issue Fixes CNDB-9443. CNDB 4.0 makes use of scheduled executors with multiple threads, for example, in `RemoteStorageHandler`: ``` sharedSSTableExecutorService = new DebuggableScheduledThreadPoolExecutor(NUM_SSTABLE_THREADS, "StorageSSTableThread", Thread.NORM_PRIORITY); ``` But CC/CC 5.0 only supports single threaded scheduled executors: ``` sharedSSTableExecutorService = executorFactory().scheduled(false, "StorageSSTableThread", Thread.NORM_PRIORITY); ``` Without this fix, `RemoteStorageHandler` is not able to load sstables fast enough to satisfy tests like `RegionBootsrapTest.testBootstrap`. ### What does this PR fix and why was it fixed This PR adds support for scheduled executors with more than one thread (pool size) as expected by CNDB.
