Added Autoscale Throughput Samples

[andrewmathew1]

Description

Added samples for both the sync and async client showing users how to create a database and container without autoscale throughput settings. Also demonstrated how to read the current autoscale throughput settings for a database and container. Lastly, these samples show a user how to update their max_throughput autoscale settings for a container.

Pull Request Overview

This PR adds comprehensive sample code demonstrating autoscale throughput management for Azure Cosmos DB. The samples show users how to create databases and containers with autoscale settings, read current throughput configurations, and update maximum throughput values.

Key Changes:

• Added synchronous client sample (autoscale_throughput_management.py) demonstrating core autoscale operations
• Added asynchronous client sample (autoscale_throughput_management_async.py) with additional concurrent operations demonstration
• Both samples include create, read, and update operations for autoscale throughput settings

The concurrency sample is probably not anything that we need to have, but won't block on that. Thanks Andrew!
