Support JSON and YAML configuration
Support new configuration options besides --flags: - JSON file through `jsonpath` - YAML file through `yamlpath` These new options are fully backwards-compatible with the existing tests. Added a new profile, 1.11-json, that expects a JSON kubelet configuration file and scores accordingly. This profile is compatible with EKS.
