ConsoleLogExporter/LogRecord.to_json repr serialization

[matthew-mcallister]

Hi, I noticed that the ConsoleLogExporter class serializes severity numbers like follows:

"severity_number": "<SeverityNumber.INFO: 9>"

This is because the LogRecord.to_json serializes the number using repr(self.severity_number). Seeing a raw Python repr in the middle of a JSON object like that is a little jarring; wouldn't it make more sense to output self.severity_number.value instead? I.e.

"severity_number": 9

Since I'm on the subject, the same could be said about the resource log field. The output format is like this:

"resource": "BoundedAttributes({'telemetry.sdk.language': 'python', 'telemetry.sdk.name': 'opentelemetry', 'telemetry.sdk.version': '1.19.0', 'service.name': 'dots-backend', 'service.instance.id': 'matthew-mbp.local:17879'}, maxlen=None)"

I feel like this could be an actual JSON object? Like

"resource": {"telemetry.sdk.language": "python", "telemetry.sdk.name": "opentelemetry", "telemetry.sdk.version": "1.19.0", "service.name": "dots-backend", "service.instance.id": "matthew-mbp.local:17879"}

Is it intuitive as to what "severity_number": 9 means as opposed to SeverityNumber.INFO? With that being said though, perhaps we may simply format our JSONs better to not use repr. Feel free to send a pr of what you think would be the most intuitive :)
