[Event Hubs Processor] Tune Log Levels for Storage (#22256)

The focus of these changes is to tune the logging level for storage
operations in order to reduce the large amount that get emitted for routine
and expected operations, such as inspecting and renewing ownership for
partitions.  These have been moved to `verbose` to reduce noise.
