At present ksync watcher does not reestablish connection when the event channel receives nil, we are using a higher level service to restart ksync on such failures.

We can make watcher restablish connections after some time if it receives a empty channel. Kubernetes API is timebound and we see this happening at fixed intervals only(every few minutes - will tell the exact no.os after test).

Slack discussion on this: https://kubernetes.slack.com/archives/C0EG7JC6T/p1582204821408400

This can be done by using https://github.com/kubernetes/client-go/blob/master/tools/watch/informerwatcher.go
