Add Microsoft integration tables and models

What does this MR do and why?

Related to #414874 (closed)

This adds two new tables and associated models so we can integrate with Microsoft Graph API.

We will only ever have one Access Token at a time. Each token lasts for 60 minutes. Once a token expires, the tenant ID, client ID and secret can be used to obtain a new one.

In a subsequent MR we will add settings to the SAML SSO settings page in the top-level group so Group Owners can configure the Application tenant ID, client ID and secret, as well as enable/disable the integration.

Then we will use these values in other issues associated with this epic - &10507.
