Dapr bulk publish - edit Dapr Cloudevent envelope via publish_metadata

[Ilai-Dabush]

In what area(s)?

/area docs

Describe the feature

The feature already exists via the single event publish. You can override certain CE fields using the publish_metadata object. In the bulk publish documentation it does not state that you can achieve the same things, but you can, via adding the Metadata map for each entry. Needs to be documented

Release Note

RELEASE NOTE: ADD override Cloudevent fields in bulk publish using the publish_metadata object documentation

Hey, I actually found out in the end that it actually didn't work. You cannot set publish metadata for a single cloud event in the bulk publish but rather to give the whole bulk the same metadata (it's got it's pros and cons but personally I need them metadata to differ for each event in some cases, especially the Kafka partition key) . I actually just found it out yesterday that we messed up the testing, and was planning on opening a new issue for that today 😳. Currently I don't have much spare time but in about 2 weeks time I wouldn't mind sparing some time to edit the documentation and state there that currently only metadata for the whole bulk of messages is supported.

Thanks
