Another tool of network sanity check

[mlycore]

Hi, I wrote a small tool for Kubernetes network connectivity check a week ago, I'd like to share this tool to your kubesanity repo, which I think would be helpful.

Here is the basic design:

As shows above, Both A and B are deployed as Daemonsets, B is also wrapped as Service X. A on every node is going to test TCP connection to B:Port, Service-X-ClusterIP:Port, NodeIP:NodePort. And finally export a general report of cluster network connectivity.

How do you think?

Sounds great, I'd love to see this added in.
