Blob storage SDK accesses `internal_response` member of HTTP response

[zooba]

azure-sdk-for-python/sdk/storage/azure-storage-blob/azure/storage/blob/_shared/policies_async.py

Line 57 in 09417f6

response.http_response.internal_response.body = response.http_response.body()

I'm not at all clear why this is necessary, but the transport I'm working on does not have a settable "body" member here, so this is causing everything to fail.

Perhaps the common response type needs a new method added? Or there's some issue with one of the existing pipelines not implementing its load_body correctly?
