Username password flow fails with WAM

[jiasli]

Describe the bug
Username password flow (also called Resource Owner Password Credentials flow) fails with WAM.

To Reproduce
Steps to reproduce the behavior:

1. Create a PublicClientApplication instance with enable_broker_on_windows=True
2. Login with acquire_token_by_username_password

Expected behavior
The login should be successful.

What you see instead

> az login --username xxx@xxx.onmicrosoft.com --password xxx
(pii). Status: Response_Status.Status_InteractionRequired, Error code: 3399614467, Tag: 508609292
Please explicitly log in with:
az login

The MSAL Python version you are using
1.24.1 from #613

Additional context
Using the same user account, acquire_token_by_username_password succeeds if enable_broker_on_windows is set to False.

I tried downgrade PyMsalRuntime and MSAL Python to older proven versions, but still ran into error. I'm stuck. Can you share some insight, Ashok Kumar Ramakrishnan (@ashok672) ?

The device authentication failed.

Reason:

• AAD is unable to authenticate the device to issue a PRT
• Please confirm the device has not been deleted or disabled in the Azure portal.

Resolution :

Follow steps listed here to re-register the device based on the device join type.

As part of #569, username password name flow bypasses broker, for now.
