      Implements test case jinterface_SUITE:node_ping/1

      Creates three OtpNode objects. One with default cookie, one with
      specified same cookie as the node running the test case and one
      with a faulty cookie. From each OtpNode object the test_server
      node is pinged.

      Also the default cookie node pings itself, and the node with the
      specified cookie pings the node with default cookie.
