Remove QueueListener and EventHub Log Noise

[RohitRanjanMS]

We identified two categories of logs in the FunctionsLogs table that provide little diagnostic value but contribute significantly to overall log volume. Removing or reducing these logs can reduce the total volume by ~10%.

1. Sending events to EventHub log (Azure SDK EventHub)
   This log contributes ~0.6% of total FunctionsLogs volume and does not offer meaningful diagnostic value.

2. QueueListener polling logs
   Polling logs generated by the QueueListener contribute ~9% of total volume and are effectively noise in most scenarios.
