We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
bash_version example doesn't work with json format
Running `insights run -p examples/rules -f json` results in a traceback because the `bash_version` rule puts an `InstalledRpm` object into its response:

```
TypeError: Object of type 'InstalledRpm' is not JSON serializable
```
