  **Added** an experimental feature to enable cluster creation on worker threads inline during requests.
  This will save memory and CPU cycles in cases where there are lots of inactive clusters and > 1 worker thread.
  This can be disabled by setting ENABLE_DEFERRED_CLUSTER_CREATION to false in agent Deployment.
