What's Changed

Disable Batching and Force Global configuration by @Baliedge in #190
- Batching functionality may be disabled by configuration Behaviors.DisableBatching = true.
  - Frees up some resources, goroutines.
  - Eliminates small delay in each request as batches are assembled and dispatched that may not be beneficial if batch size is typically small.
- Force global behavior on all rate checks by configuration Behaviors.ForceGlobal = true.
  - Global behavior is unaffected by DisableBatching setting.
- Change GlobalSyncWait default from 500µs to 500ms to reduce global sync traffic.
- Remove unnecessary buffer from WorkerPool command channels.
- Remove extraneous tracing detail.
- Metric updates
  - WorkerPool metrics:
    - Renamed gubnernator_pool_queue_length to gubernator_worker_queue_length.
    - Added gubernator_command_counter: Counter of commands executed in WorkerPool.
    - Removed gubernator_check_counter.
      - Redundant. Use gubernator_getratelimit_counter{calltype="local"}.
  - Global behavior metrics:
    - Added gubernator_global_queue_length: Size of global broadcast queue.
    - Renamed gubernator_broadcast_durations to gubernator_broadcast_duration.
    - Added gubernator_broadcast_counter: Rate of global broadcasts. Label condition may be timer|queue_full to indicate what triggered the broadcast.
    - Changed gubernator_concurrent_checks_counter from summary to gauge type.
  - Batch behavior metrics:
    - Renamed gubernator_async_durations to gubernator_batch_send_duration.
    - Renamed gubernator_asyncrequest_retries to gubernator_batch_retries.
    - Renamed gubernator_queue_length to gubernator_batch_queue_length.
      - Changed from summary to gauge type.
