Scale up test workload for Cosmos Python SDK for DR Drill and performance testing

• Scale up test workload for Cosmos Python SDK for DR Drill and performance testing
• We will address any gaps in the SDK related to write region failover and offline region features. The latest SDK version has been tested with some staging accounts, and we are working on an in-house repro with different setups including Envoy Proxy to be able to test these features on bigger customer scale. We will continue thorough testing to ensure no gaps remain and fix any that arise.
