[azure logs] use one input + routing for all data streams (WIP)

[zmoog]

Proposed commit message

Switch the integration package from the one-input-per-data-stream model to the one-input model.

One input per data stream model:

One input model:

In the one-input model, there is only one azure-eventhub input running and sending events to the events data stream. In the events data stream, the ingest pipeline performs these tasks:

• discover and set the event.dataset field using the category field in the event.
• use the event.dataset field to reroute the event to the target data stream.

The discover process uses the following logic:

• if the event doesn't have a category, it sets event.dataset to azure.eventhub (the generic integration)
• if the event does have a category, it sets event.dataset to azure.platformlogs (it's probably an Azure log)
• if the event category is supported, it sets event.dataset to specific one like azure.activitylogs or azure.signinlogs.

After the discovery step, the routing rules use the event.dataset value to forward the events to the best available target data stream.

Here's the latest iteration for the integration settings to evidence the recommended single data stream (v2) vs. the legacy multiple data stream (v1) solutions:

@zmoog - do you have any updates as to the timeframe when this will be ready / released?

Hey @defutek-tj, my apologies for the delay.

We clarified the Event Hub SDK behavior with the Event Hub team, and now we can move forward with the first update.

In the following integration update, we will ship a new data stream v2 (preview) to handle all the log categories. ETA is next week.
