Missing agent.name field

[rlapond]

Hi,

The endpoint datastreams are missing the agent.name field in the documents. Normally any document ingested by Elastic Agent using an Integration has agent.name available.

For some datastreams agent.name already exists in the mapping:

@pierrehilbert Endpoint does not know the value to use for agent.name. For fields like this, to make sure Endpoint stays in sync with Agent/Beats, Agent has populated a field like fleet.agent.* in the config it sends to Endpoint. Can we do that for fleet.agent.name too?
