Client set up for Givernment cloud

Initially raised by @cjsucko in #672

The setup here gives an error around getting an authorization token, pointing to a bug in client initialization

from azure.identity import AzureAuthorityHosts
from azure.identity.aio import ClientSecretCredential
from msgraph import GraphServiceClient

auth = {
 # DICT holding 'tenant ID',  'client ID', 'client secret key'
}

credential = ClientSecretCredential(
    auth['tenant'],
    auth['clientId'],
    auth['clientSecret'],
    authority=AzureAuthorityHosts.AZURE_GOVERNMENT
)

scopes = ['https://graph.microsoft.us/.default']
client = GraphServiceClient(credentials=credential, scopes=scopes)

users = await client.users.get() # <--- Error on this line

With a few tweaks to add scopes and authority:

redential = ClientSecretCredential(
    auth['tenant_id'],
    client_id=auth['clientId'],
    client_secret=auth['clientSecret'],
    authority=os.getenv('authority'),
   )
)
scopes = ['https://graph.microsoft.com/.default']
client = GraphServiceClient(credentials=credential, scopes=scopes)
print(client.request_adapter)


async def get_users():
    try:
        users = await client.users.get()  # <--- Error on this line
        for user in users.value:
            print(f"User: {user.display_name} {user.id}")
    except APIError as e:
        print(f"Error: {e}")

The error persists as:

• Unable to parse claims response on get()

A workaround, the request adapter will fall back on the public graph URL, to fix this wen using government cloud, use:

        adapter = GraphRequestAdapter(auth_provider=auth_provider, client=http_client)
        adapter.base_url = 'https://graph.microsoft.us/v1.0'
        self.client = GraphServiceClient(request_adapter=adapter, scopes=self.scopes)
