Move this code into the plug-in manager itself so that others can re-use it from "plugin list --json". Might be nice to take a `pattern` to list only some plug-ins. 

```
json::Object PluginManager::GetJSON(StringRef pattern);
```

Where if pattern in empty, it will match everything and the JSON will contain everything, but if it contains "system-runtime" then it will return JSON for only that pattern. Make this easy to plug-in to "plugin list --json"
