Boaz Leskes b605184471 Recovery: add total operations to the _recovery API
This commit adds the current total number of translog operations to the recovery reporting API. We also expose the recovered / total percentage:

```
"translog": {
   "recovered": 536,
   "total": 986,
   "percent": "54.3%",
   "total_time": "2ms",
   "total_time_in_millis": 2
},
```
