Scanning GovCloud for all Services Ends in JSON Serialization Error, Truncated Output

- Version: `1.1.1`
- Local OS Version: `Ubuntu 20.04.5 LTS`
- Local chip architecture: `x86_64`
- Reproduces in: `432896750513`

Steps to Reproduce:

1. python3 scan.py -s scan/sample/all_services.json -r us-gov-west-1

`output:`
```
INFO:__main__:Finished processing for region: us-gov-west-1
ERROR:__main__:'us-gov-west-1' generated an exception: Object of type bytes is not JSON serializable

```

Start with scan.py at main's json.dump call around line 334 and the DateTimeEncoder.default method around line 44. Reproduce the issue with the provided python3 scan.py command for us-gov-west-1, then trace the bytes value in service_result["result"]. Done means the GovCloud scan completes without a JSON serialization error and produces the full output.
