      Description

      Track stats on number of waiting requests/acquires per state, per lock, and active threads/ops per state, like we do for the globalLock section. 

                      "currentQueue" : {
      		 
      			"total" : 205,
      		 
      			"readers" : 200,
      		 
      			"writers" : 5
      		 
      		},
      		 
      		"activeClients" : {
      		 
      			"total" : 100,
      		 
      			"readers" : 100,
      		 
      			"writers" : 0
      		 
      		}

      Also, need stats on the number of acquires/transitions for each locks + state. How many times was the read lock (for each lock instance) acquired and released?
