Adds support for batch addition of sanitizers https://github.com/Azure/azure-sdk-tools/tree/main/tools/test-proxy/Azure.Sdk.Tools.TestProxy#passing-sanitizers-in-bulk

I didn't know we could do this, this is way better than adding each sanitizer individually.

This feature was added more than six months after the JS recorder was built it seems. @timovv

In what order does the test proxy apply the sanitizers when using this bulk operation? Is it in the order they appear in the request?

Scott says yes.
