Other Changes
- Changed the default concurrency upload count from 5 to Math.Clamp(Environment.ProcessorCount * 2, 8, 32). This controls the maximum number of concurrent tasks that will be used during large uploads, and this change should result in higher throughput for these operations by default in most environments. This can be reverted by enabling "Azure.Storage.UseLegacyDefaultConcurrency" in the AppContext switch or "AZURE_STORAGE_USE_LEGACY_DEFAULT_CONCURRENCY" in the environment variable.
