ARM, test case for redirecting resource

[XiaofeiCao]

doc: https://github.com/cloud-and-ai-microsoft/resource-provider-contract/blob/14f7fcee55c7387a0c6d89d742794967c8f4e130/v1.0/common-api-details.md#redirecting-the-client

Need a real case scenario for this test.

I could think of one scenario, though no idea how to implement it:

• GET a resource
• backend return 307 with Location header pointing to another resource's URL
• GET the resource by the URL
