Service crash on ws failure

[avoylenko]

If the RTPENGINE_URL env points to the wrong endpoint or there is an issue with WS establishment, the service crashed with the below error:

7|sbc-rtpengine-sidecar  | Error: connect ECONNREFUSED 127.0.0.1:8082
7|sbc-rtpengine-sidecar  |     at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1555:16) {
7|sbc-rtpengine-sidecar  |   errno: -111,
7|sbc-rtpengine-sidecar  |   code: 'ECONNREFUSED',
7|sbc-rtpengine-sidecar  |   syscall: 'connect',
7|sbc-rtpengine-sidecar  |   address: '127.0.0.1',
7|sbc-rtpengine-sidecar  |   port: 8082
7|sbc-rtpengine-sidecar  | }

probably good that it crashes though if misconfgured, silently continuing with configuration error doesnt seem like a good idea to me

The ws connection is needed just to dump the rtpenigne stats. Is this so important for the service?
