See parent task.

AT:

• the Optimize Cloud Events API is documented and replaces the current Ingest API documentation
• Currently there is no 1:1 match in the CloudEvents Specification or any of it's existing extensions to reflect the traceId or the group property on the Optimize Ingestion API.
  • we define the traceId as a required extension context attribute
  • we define group as an optional extension context attribute

Out of scope:

• CloudEvents authorization requirements will be addressed with OPT-3152
