Add link from previous trace when publishing messages with pika #3047
Description
What problem do you want to solve?
From my understanding of messaging-spans, when a producer publishes a message, its span would be linked with the span of the consumers. This does not seem to happen when using opentelemetry-instrumentation-pika.
Describe the solution you'd like
The _decorate_basic_publish should take care of automatically adding links.
Describe alternatives you've considered
I tried to manually implement creation of links, but since the decorator function is not public, I did not understand how this could be done.
