• Package Name: azure-mgmt-resource
• Package Version: 17.0.0
• Operating System: linux
• Python Version: 3.8.0

Describe the bug

Many methods in azure-mgmt-resource no longer provide the results as a nested object, rather the results are provided as a str. This was not included in the breaking change documentation in this release.

It appears that this change was made in #18686.

To Reproduce

resource = ResourceManagementClient(...).resources.get_by_id(resource_id, "2018-11-30")
resource.properties['principalId']

Expected behavior

Previously, this returned the dictionary with the keys tenantId, principalId, and clientId.

Now, this returns a string with the value {'tenantId': 'GUID', 'principalId': 'GUID', 'clientId': 'GUID'}.

Note, because this string uses single quotes, it can't be decoded as json, like many other resources from Azure.
