Naveen Naidu f55df228fe Server: Add Event Trigger Metrics
- [x] **Event Triggers Metrics**
  - [x] Distribution of size of event trigger fetches / Number of events fetched in the last `event trigger fetch`
  - [x] Event Triggers: Number of event trigger HTTP workers in process
  - [x]  Event Triggers: Avg event trigger lock time (if an event has been fetched but not processed because http worker is not free)

#### Sample response
The metrics can be viewed from the `/dev/ekg` endpoint

```json
{
"num_events_fetched":{
      "max":0,
      "mean":0,
      "count":1,
      "min":0,
      "variance":null,
      "type":"d",
      "sum":0
   },
 "num_event_trigger_http_workers":{
      "type":"g",
      "val":0
   },
"event_lock_time":{
      "max":0,
      "mean":0,
      "count":0,
      "min":0,
      "variance":0,
      "type":"d",
      "sum":0
   },
```

#### Todo
- [ ]  Group similar metrics together (Eg: Group all the metrics related to Event trigger, How do we do it??)
