✨ [New]: pass cancellation token to test fixtures

[stijnmoreels]

Description

With the new update of xUnit and the update throughout other testing frameworks as well, there is support available for test cancellation. This makes sure that tests cancelled by the user are faster finished (still keeping the teardown process in mind).

Solution

We should make sure that the following libraries have test cancellation support:

• Azure Blob Storage chore(blob): add cancellation token support to az blob storage test fixtures #508
• Azure Table Storage
• Azure Service Bus
• Azure Event Hubs
• Azure Cosmos DB
• Azure Data Factory
• Core
• Azure File Share

Additional context

The process of adding cancellation support is:

1. Determine the 'setup' operations on the test fixture.
2. Create new overloads with the CancellationToken parameter.
3. Use the CancellationToken parameter throughout the 'setup' operations.
4. Mark the non-cancellation overloads obsolete & replace implementation with delegation to cancellation-supported overloads.
