Description of the change

Adds a post method to the exporter to post payloads returned from toPayload.

This is an incremental update moving toward

• renaming the existing export method to exportToQueue
• adding a new export method that encapsulates the functionality of export, toPayload and post. This will allow spans to be sent immediately when ended.
• ReplayManager can now call post through tracing.exporter, participating in any additional handling there for all spans (e.g. request headers).

Type of change

• New feature (non-breaking change that adds functionality)
