Upgrade to a newer version of `azure-storage-blob`

[ant0nsc]

Feature Request Description

We are using blobxfer as part of a larger codebase, where some of the libraries require a newer version of azure-storage-blob>=12.0.0. We have no immediate way of continuing our development, since we clearly cannot require old versions of azure-storage-blob (for blobxfer) and newer versions (for azureml-mlflow) to be present at the same time.

Describe Preferred Solution

It would be great to update blobxfer to use the latest version of azure-storage-blob.

Describe Alternatives Considered

I don't immediately see an alternative.

This is a large breaking change. If you're using blobxfer-cli then please use a virtualenv to isolate (or use the binary).
