analyzer: goldpinger pingmap

[adamancini]

Describe the rationale for the suggested feature.

Be able to immediately report on the state of cluster networking - a huge help with joining additional nodes to kURL, or with identifying networking issues that affect CNI but not host networking. Today, we collect the goldpinger results if it is installed, but we do not analyze it.

Describe the feature
Analyze the results of the goldpinger addon's pingmap - result is a nested JSON object with results of the HTTP query to each other goldpinger pod's API.

could probably use /cluster_health and /check_all for analysis
