Fix GEODE-154: HDFS region with HeapLRU reports LowMemoryExceptions
even when region size is less then the eviction threshold
- calling setUsageThreshold() on MemoryPoolMXBean resulted in
it reporting incorrect memory usage causing temporary spikes.
Since we already set CollectionThreshold at 1 byte and also have a
stat and heap poller thread, we now skip setting the usage threshold.
