    Description

      This will a per-instance class that will handle all interactions between the Resharding/Global indexes metrics and external callers.

      This is a simple example of what it could look like:

      class IndividualMetrics {
      	std::atomic<counter> _onlyIndividualsNeed;
      	SharedMetricsPtr _sharedMetrics;
      	CumulativeMetricsPtr _parent;
      	
      	IndividualMetrics(OperationContext* opCtx) {
      		_parent = CumulativeMetrics::get(opCtx->getServiceContext());
              _sharedMetrics = _parent.createRegisteredSharedMetrics()
      	}
      	
      	~IndividualMetrics() {
      		_parent.deregisterSharedMetrics(_sharedMetrics);
      	}
      }
