Entra conditional access: Add logging between Fleet proxy (fleetdm.com) and Microsoft

[noahtalerman]

• @noahtalerman: Can we please add logs of the communication (requests) between the Fleet proxy and all the Microsoft tools? (Intune, Microsoft Graph, etc.). Why? In dogfood, we're finding that some hosts never get marked as non-compliant while others do.
• @mikermcneil: Just an idea, but could add sails.log() with an easy to search prefix (assuming debug log level is on)
• @lucasmrod: Also we will need logging of the Intune group we end up selecting for applying the "conditional access policy". We would like to see which group is assigned the policy. E.g. we deleted the "All company" group, what happens if the proxy used that one to set the policy? But we want to confirm it selected the right group:
