Improved Error handling

[vincenttran-msft]

Currently, this is the usage patterns when encountering an error:

stdout:

Base error: server returned error status which will not be retried: 404
Status code: 404
Error kind: HttpResponse(NotFound, "ContainerNotFound")
Inner error kind: HttpResponse(NotFound, "ContainerNotFound")

Therefore, the two main asks to improve error handling are:

1. Exposing the raw response (so that we can get all the information returned from the service)
2. Ideally: A standard Azure Error deserialization model supported through Azure Core

Although there are several Storage specific errors (and thus several different forms the XML bodies can take), we are curious as to whether a standard Azure Error deserialization model would help to standardize error handling or at the very least simplify implementation for library-specific error models.
Thanks!
