Updating azure sdk version

[sergenyalcin]

provider-azure uses an old version of azure go sdk. Updating this sdk can be a mandatory case in future. Also, with this change, we can use the new api versions of resources and we can implement new added resources.

For details of another important point about this issue, please see: #322

MS suggests that using the new authorization package: azidentity.

This package is in azure go sdk repo and if we want to consume this new auth tool, we need to update the our sdk version.
