   I took a look at 2.1.0-SNAPSHOTS properties and opened #2271 as a result of noticing that a lot of the props that could use metrics were all thread pools.  Other than that I found the following props need further exploration to see if they could benefit from having metrics to help tune them.  Some of these may not make sense for metrics, I just took any that I thought may. I plan to work down the following list opening individual issues for ones where it does make sense after investigating them individually.
   
   ```
   compaction.coordinator.compaction.finalizer.check.interval
   compaction.coordinator.compactor.dead.check.interval
   compaction.coordinator.message.size.max
   compactor.message.size.max
   gc.candidate.batch.size
   gc.cycle.delay
   manager.startup.tserver.avail.max.wait
   manager.startup.tserver.avail.min.count
   table.bloom.load.threshold
   table.bulk.max.tablets
   table.cache.block.enable
   table.cache.index.enable
   table.durability
   table.file.max
   table.scan.max.memory
   tserver.cache.data.size
   tserver.cache.index.size
   tserver.cache.summary.size
   tserver.files.open.idle
   tserver.memory.maps.max
   tserver.wal.max.age
   tserver.wal.max.referenced
   tserver.total.mutation.queue.max
   tserver.slow.filepermit.time
   tserver.slow.flush.time
   tserver.server.message.size.max
   tserver.scan.files.open.max
   ```
