Description

Azure Services support two different set of APIs.
Blob: https://learn.microsoft.com/en-us/rest/api/storageservices/blob-service-rest-api 
DFS: https://learn.microsoft.com/en-us/rest/api/storageservices/datalakestoragegen2/operation-groups 

As per the plan in HADOOP-19179, this task enables ABFS Driver to work with both set of APIs as per the requirement.

Scope of this task is to refactor the ABfsClient so that ABFSStore can choose to interact with the client it wants based on the endpoint configured by user.

The blob endpoint support will remain "Unsupported" until the whole code is checked-in and well tested.
