Daemonize ZkBucketDataAccessor GC_THREAD (#1936)

GC_THREAD (which is actually an ExecutorService, not Thread) is a static field in ZkBucketDataAccessor. The executor is started when ZkBucketDataAccessor class is initialized but it is never shut down. Since ExecutorService threads are generally not daemon threads, not shutting down GC_THREAD prevents JVM from shutting down cleanly.

This commit makes ZkBucketDataAccessor GC_THREAD a daemon thread so it doesn't prevent application shutdown.
