[Feature] Add Azure AD Group Memberships to User Metadata

[parthbs]

This PR updates the oauth_providers.py file to include Azure Active Directory (Azure AD) group memberships in the user metadata.

The following changes were made:

1. Fetch Group Memberships: Added logic to retrieve group memberships using the Microsoft Graph API.
2. Error Handling: Implemented a try-except block to gracefully handle any errors during the group membership fetch process.
3. User Metadata Update: Updated the User object to include the fetched group memberships under the groups key in the metadata.

Testing:

• Verified that group memberships are correctly fetched and added to the user metadata.
• Tested error handling to ensure the application continues to function if the group membership fetch fails.

Dependencies:

• No new dependencies were added.

Notes:

• This change ensures that user group memberships are available for downstream processes that rely on user metadata.
• Backward compatibility is maintained as errors during group membership fetch are ignored.

@parthbs can we put this under a Boolean parameter in @cl.login? My company has 10s of thousands of groups for some reason and this could blow up the metadata for some.

@willydouhard can you check this PR now?

I see that you initialise a user_data variable but I was talking about user_group

@parthbs you can retrieve group memberships using the token this already retrieves. No need to force this into the framework when most users won't need this.
