Description:

Put HTTP headers in Jaeger receiver into context object. I need to access haeders in a custom processor to attach tenant ID into span attributes and calculate some metrics.

Also https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/master/processor/routingprocessor uses metadata to access tenant ID header.

FYI in the meantime, we have applied the patch to our fork to unblock us hypertrace/hypertrace-collector#23. It would be great to move this PR to decrease maintenance pain.

Not sure which headers do you need access to, but there are some information we add related to tenant id (https://github.com/open-telemetry/opentelemetry-collector/blob/main/client/client.go), also there is this discussion #2495

The problem with context is that we drop it in processors like batch.

X-tenant-id is the header name. Our collector is behind proxy that handles auth and injects this header if the access is allowed.

The problem with context is that we drop it in processors like batch.

It's is not an issue for us since we access the headers in the first processor in the pipeline.
