DataFactoryManagementClient() authentication fails when using DefaultAzureCredential?

[SeaDude]

• Package Name: azure.mgmt.datafactory
• Package Version: azure-mgmt-datafactory==0.13.0
• Operating System: Unbuntu 20
• Python Version: 3.8.5

Describe the bug
I use DefaultAzureCredential for all Python dev up to this point (KeyVault clients, BlobStorage clients, etc). This is my first time working with azure.mgmt.datafactory in Python. When trying to use DefaultAzureCredential, I get the error: AttributeError: 'DefaultAzureCredential' object has no attribute 'signed_session'.

To Reproduce
Steps to reproduce the behavior:

credential = DefaultAzureCredential()
resource_client = ResourceManagementClient(credential, subscription_id)
adf_client = DataFactoryManagementClient(credential, subscription_id)
rg_name = 'RG_ADF_SANDBOX1'
df_name = 'df20201019test'
df_resource = Factory(location='westus')
df = adf_client.factories.create_or_update(rg_name, df_name, df_resource) #<----ERROR HERE

Expected behavior
The DefaultAzureCredential cred chain would be used to authenticate DataFactoryManagementClient().

This issue is addressed here: https://docs.microsoft.com/en-us/azure/developer/python/azure-sdk-authenticate?tabs=cmd

Search "Using DefaultAzureCredential with SDK management libraries" on this page and it will take you to the section that gives more information to resolve this issue.

It can be resolved by using Wrapper Classes.

Thank you for the link @Ganeshbhargav. I don't understand how the wrapper works, so I probably won't incorporate it into my code. I'll stick to ServicePrincipalCredentials (I think thats what its called) until DefaultAzureCredential is implemented for this library.

@lmazuel should the link on this docs page lead to https://github.com/jongio/azidext#python instead? It seems to have additional instructions to help make things easier to incorporate
