General connectivity test

Kuberang is a simple but efficient way to quickly check cluster network connectivity. To quote from the project's README:

Quote from GitHub apprenda/kuberang README.md:

  • Has kubectl installed correctly with access controls
  • Has active kubernetes namespace (if specified)
  • Has available workers
  • Has working pod & service networks
  • Has working pod <-> pod DNS
  • Has working master(s)
  • Has the ability to access pods and services from the node you run it on.

You can run it:
