Batch exporter doesn't work with children of forked processes

[jpmelos]

Describe your environment
Python 3.6.9
python-opentelemetry 0.16b1

Steps to reproduce
Instrument your app using the batch exporter as a span processor:

    trace.get_tracer_provider().add_span_processor(
        BatchExportSpanProcessor(
            jaeger.JaegerSpanExporter(
                service_name=app.config['DEPLOYMENT_NAME'] or 'other',
                agent_host_name=jaeger_agent_host,
                agent_port=jaeger_agent_port,
            ),
            max_export_batch_size=SPAN_BATCH_MAX_SIZE,
        )
    )

Then, fork the process.

What is the expected behavior?
Sending traces and spans from the children of a forked process would work.

What is the actual behavior?
The child process can't send traces and spans.

@jpmelos this is kind of limitation; You need to use fork hooks such as uWSGI uwsgidecorators.postfork, Gunicorn post_fork and os.register_at_fork.
