Parsing console output json objects into ReadableSpan objects

Is your feature request related to a problem?

I would like to be able to easily parse span objects outputted to stdout via ConsoleSpanExporter into actual span objects with which I can manually export via opentelemetry.

Describe the solution you'd like

Add a ReadableSpan.from_json(XXX) or ReadableSpan.from_dict

Describe alternatives you've considered

No response

Additional Context

I'm writing a script to instrument bash commands during CI. There is currently overhead when exporting to a remote GRPC otel server (while using the python library).

I'm currently writing a python equivalent of otel-cli and I would like to write out console spans to a file/directory and then re-export these spans at the end of a CI pipeline or upload them as an artifact to be parsed by a python library.

Would you like to implement a fix?

None

Start by reviewing ReadableSpan and ConsoleSpanExporter, then inspect the JSON-shaped span output described in the issue and how spans are manually exported through the OpenTelemetry Python library. Done means console output can be parsed into ReadableSpan objects that can be re-exported, with behavior documented and covered by tests.
