**Description**
It would be nice if the azure-storage-blob dependency for apache-airflow-providers-microsoft-azure was upgraded to a more recent version that 2.1.0. 

**Use case / motivation**

The version 12.4.0 will allow us to perform OAuth refresh token operations for long running tasks. We use this to authenticate against our datalake, and it's currently not possible with the version 2.1.0 that airflow uses. 


**Related Issues**

The 12.x version is 100% incompatible with the 2.x versions. The API has changed drastically between the two versions, so all the airflow azure operators will need to be changed and fixed.
