added a new path for http stats

1. Created a new path parameter for the endpoint to emit http statistics "/stats"

```
$ curl -s http://localhost:8080/stats

{"uptime":{"length":1001143195704,"unit":{}},"totalRequests":6,"openRequests":1,"maxOpenRequests":1,"totalConnections":6,"openConnections":1,"maxOpenConnections":1,"requestTimeouts":0}

```
