[Heartbeat] Handle data streams (#24223)
Handles data streams from fleet, the current heartbeat code doesn't handle data_streams at all, this fixes that. Additionally, it hoists the id from the top level of the yaml config, and merges both levels of data_streams, since one is at the input level, and the other is at the stream level.
Additionally, this cleans up the data streams code significantly, introducing a new add_data_streams_index processor that:
More efficiently formats index names for data streams
Allows individual events to override the dataset (useful for synthetics where we have a base browser dataset, but also browser_screenshot and browser_network for extended data that can take up lots of space, and often requires a different ILM policy).- Loading branch information
