Commit Message

vinyl: keep track of thread pool idle ratio

To understand whether the disk is fully utilized or can still handle
more compaction load and make right decisions regarding transaction
throttling, we need a metric that would report how much time worker
threads spent being idle. So this patch adds two new metrics to global
statistics, disk.dump_idle_ratio and compact_idle_ratio, which show how
much time dump threads and compaction threads were idle, respectively.
The metrics are updated using the following formula:

                       idle_time
  idle_ratio = --------------------------
               dump_period * worker_count

where idle_time is the total amount of time workers were idle between
the last two dumps, dump_period is the time that passed between the last
two dumps, worker_count is the number of workers in the pool.
