Describe the enhancement:
The Azure Logs integration (and related logs integrations) has used azure-eventhub processor v1 for years. This processor is based on the legacy Event Hubs SDK.

We later introduced azure-eventhub processor v2 as an option, but kept processor v1 as the default.

Since we've decided to retire processor v1, we plan to set processor v2 as the default option in the next release, and completely remove v1 in the following release.
